Locally, it appears that I have Postgresql 9.2.4 installed. I am guessing based off the last error message I received that I do not have the latest version:
pg_dump: server version: 9.3.1; pg_dump version: 9.2.4
pg_dump: aborting because of server version mismatch
On other posts here, what was told to do was to add the following the the .profile and then run the command:
export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
. ~/.profile
which did not work.
2 weeks ago, I installed Postgresql with the simple command:
brew install postgresql
and that gave me the version I currently have. It appears as I don't have the latest version then.
How can I a) upgrade to 9.3.1 (which is what the server version looks to be) or b) do one of these fixes like the one I attempted above which did not work.
I am very new to Postgresql so a step by step would be very helpful for me.
brew upgrade postgresql
brew link --overwrite postgresql
Solved by adding this at the end of my ~/.bash_profile ( or ~/.zshrc for zsh)
export PG_DUMP="/Applications/Postgres.app/Contents/Versions/9.6/bin/"
PATH=$PG_DUMP:$PATH
Don't forget to run (for bash shell)
$ source ~/.bash_profile
or (for zsh)
$ source ~/.zshrc
You can check the path of pg_dump by running
$ which pg_dump
==> /Applications/Postgres.app/Contents/Versions/9.6/bin//pg_dump
MacOS Mojave (10.14.2)
Postgres.app (2.1.5)
PostgreSQL 9.6
There are upgrade instructions you have to follow between Postgresql 9.2 and 9.3...
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
mv /usr/local/var/postgres /usr/local/var/postgres92
brew update
brew upgrade postgresql
initdb /usr/local/var/postgres -E utf8
pg_upgrade -b /usr/local/Cellar/postgresql/9.2.4/bin -B /usr/local/Cellar/postgresql/9.3.1/bin -d /usr/local/var/postgres92 -D /usr/local/var/postgres
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

I've installed mysql 5.7 via brew. The binary files are installed at /usr/local/opt/mysql\#5.7/bin/ however I can't access these files as this location isn't in my path.
Is there a brew way to fix this rather than me making symlinks around the system myself?
The Homebrew way of "fixing" this is to use link --force:
brew link --force mysql#5.7
Alternatively, you can add this location to your $PATH by modifying it in your ~/.bashrc or ~/.bash_profile:
export PATH="$(brew --prefix mysql#5.7):$PATH"
The simple "brew way" to do this is answered here
$ brew info mysql (to get info about the installed versions)
$ brew switch mysql 5.7.21 (to switch to a stable version)
Official page do not mention such case. But many users need only psql without a local database (I have it on AWS). Brew do not have psql.
You could also use homebrew to install libpq.
brew install libpq
This would give you psql, pg_dump and a whole bunch of other client utilities without installing Postgres.
Unfortunately since it provides some of the same utilities as are included in the full postgresql package, brew installs it "keg-only" which means it isn't in the PATH by default. Homebrew will spit out some information on how to add it to your PATH after installation. In my case it was this:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
Alternatively, you can create symlinks for the utilities you need. E.g.:
ln -s /usr/local/Cellar/libpq/10.3/bin/psql /usr/local/bin/psql
Note: used installed version instead of 10.3.
Alternatively, you could instruct homebrew to "link all of its binaries to the PATH anyway"
brew link --force libpq
but then you'd be unable to install the postgresql package later.
libpq 11.2
MacOS & zsh or bash
below works
install libpq
brew install libpq
update PATH
if use zsh:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
if use bash:
echo 'export PATH="/usr/local/opt/libpq/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
Homebrew only really has the postgres formula, and doesn't have any specific formula that only installs the psql tool.
So the "correct way" to get the psql application is indeed to install the postgres formula, and you'll see toward the bottom of the "caveats" section that it doesn't actually run the database, it just puts the files on your system:
$ brew install postgres

<snip>
To have launchd start postgresql now and restart at login:
brew services start postgresql
Or, if you don't want/need a background service you can just run:
pg_ctl -D /usr/local/var/postgres start
==> Summary
🍺 /usr/local/Cellar/postgresql/9.6.5: 3,269 files, 36.7MB
Now you can use psql to connect to remote Postgres servers, and won't be running a local one, although you could if you really wanted to.
To verify that the local postgres daemon isn't running, check your installed homebrew services:
$ brew services list
Name Status User Plist
mysql stopped
postgresql stopped
If you don't have Homebrew Services installed, just
$ brew tap homebrew/services
...and you'll get this functionality. For more information on Homebrew Services, read this excellent blog post that explains how it works.
If you truly don't need postgresql then you don't even have to alter your path to use libra, just link libpq. The docs say the only reason it isn't is to avoid conflicts with the PostgreSQL package.
brew uninstall postgresql
brew install libpq
brew link --force libpq
Install libpq:
brew install libpq
Then, create a symlink:
sudo ln -s $(brew --prefix)/opt/libpq/bin/psql /usr/local/bin/psql
Hope it helps.
I found all of these really unsatisfying, especially if you have to support multiple versions of postgres. A MUCH easier solution is to download the binaries here:
https://www.enterprisedb.com/download-postgresql-binaries
And simply run the executable version of psql that matches the database you're working against without any extra steps.
example:
./path/to/specific/version/bin/psql -c '\x' -c 'SELECT * FROM foo;'
Found so many useful answers here, but a bit outdated since homebrew moved the installation files to /opt/homebrew/Cellar/libpq/15.1. After libpq is installed with brew install libpq you can run below command to see new location
brew link --force libpq
Then you can add it to your zshrc with
echo 'export PATH="/opt/homebrew/Cellar/libpq/15.1/bin:$PATH"' >> ~/.zshrc
You could try brew install postgresql
But this provides a nice GUI to manage your databases https://postgresapp.com
I'm using Mac OS X 10.8.5 and trying to install postgreSQL using homebrew. I've fixed several errors and warnings which have occurred when I ran brew info postgresql. However, I don't know how to fix the rest of the problems.

If builds of PostgreSQL 9 are failing and you have version 8.x installed,
you may need to remove the previous version first. See:
https://github.com/Homebrew/homebrew/issues/issue/2510
To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
http://www.postgresql.org/docs/9.3/static/upgrading.html
When installing the postgres gem, including ARCHFLAGS is recommended:
ARCHFLAGS="-arch x86_64" gem install pg
To install gems without sudo, see the Homebrew wiki.
To have launchd start postgresql at login:
ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
Then to load postgresql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
Or, if you don't want/need launchctl, you can just run:
postgres -D /usr/local/var/postgres
When I run server, I get:
/usr/local/rvm/gems/ruby-2.0.0-p353/gems/activerecord-4.0.0/lib/active_record/connection_adapters/postgresql_adapter.rb:825:in `initialize': could not connect to server: No such file or directory (PG::ConnectionBad)
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
I've uninstalled postgresql and reinstalled but seems like I wasn't able to remove the postgresql 8.x version.
I've read several different posts to install and run postgreSQL properly and tried what they've suggested but nothing seems to be working for me.
Installing PostgreSQL in Mac OS X El Capitan using homebrew
First check the 'owner' of the folder '/usr/local' by using this command:
$ ls -la '/usr'
If the owner of the file is 'root', run this command to change the owner to your currently logged user:
$ sudo chown -R `whoami` /usr/local
Install PostgreSQL using homebrew:
$ brew update
$ brew doctor
$ brew install postgresql#15
and that's it!
Uninstall PostgreSQL using homebrew:
$ brew uninstall postgres
then remove this folder: '/usr/local/var/postgres' and then change back the owner of your local
local folder to:
$ sudo chown -R root /usr/local
How to:
List brew services: $ brew services list
Run brew services: $ brew services start <service_name>
ex: $ brew services start postgresql
Stop brew serices: $ brew services stop <service_name>
Logging in to PostgreSQL for the first time:
1.) Run the postgres: $ brew services star postgresql
2.) Create a db using your username: $ createdb `whoami`
3.) Login to postgres: $ psql
To quit psql, just type: \q
4.) Create database (using terminal):
$ createdb <db_name>

Optional, installing pgAdmin:
1.) Download pdadmin: https://www.pgadmin.org/download/macosx.php
2.) Press ctrl+click then open to run the dmg file then drag it to your
Application folder. ctrl+click the pdadmin to run it so that it won't
ask for that annoying question again.
Login in to pgAdmin:
Note: Use your username and password when you installed your postgres for first login
then create a new user with privileges later or just change your password from
'File -> Change Password...'
Your Ruby code is apparently linked against the system version of PostgreSQL, which looks for a socket in /var/pgsql_socket. The Homebrew version would look in /tmp. (At this point, make sure that a file like /tmp/.s.PGSQL.5432 exists.) To work around this, you can tell your code to connect to the Homebrew version by specifying /tmp with the "host" option, however your code spells that.
In the future, make sure your Ruby gems are linked against the Homebrew version. Perhaps just uninstalling and reinstalling with the right paths set would do it.
I have installed Redis via gems, but am having a problem getting it started.
Following James Edward Gary II steps http://blog.grayproductions.net/articles/setting_up_the_redis_server/
I have:
$ sudo gem install ezmobius-redis
Password:
Successfully installed ezmobius-redis-0.1
1 gem installed
Installing ri documentation for ezmobius-redis-0.1...
Installing RDoc documentation for ezmobius-redis-0.1...
$ redis-server path/to/redis.conf
-bash: redis-server: command not found
Any thoughts as to what I am missing?
If you have done just what you have described in your question, then you are missing redis. ezmobius-redis is just a Ruby library that allows connecting to redis. redis itself is a separate piece of software running independently.
If you followed the article you linked and if you especially did this:
curl -O http://redis.googlecode.com/files/redis-1.0.tar.gz
tar xzvf redis-1.0.tar.gz
cd redis-1.0
make
sudo cp redis-server redis-cli redis-benchmark /usr/local/bin
then you have actually installed a very old version of redis into the /usr/local directory.
If you did this starting the server did not work, then you probably have /usr/local not in your PATH. You can start the server using:
$ /usr/local/bin/redis-server path/to/redis.conf
However, I would suggest to install the newest version of redis. To do that on OSX you should use homebrew:
- Read this (https://github.com/mxcl/homebrew/wiki/Installation) as a guide on how to install homebrew and then do a
brew install redis
to install the newest version of redis.
You might need to open a new terminal to get the latest path settings. Try typing "bash" or "xterm &" and typing the redis-server command again.
I know there are a lot of lion-postgresql related questions on stack overflow already, but none seem to solve my problem.
I installed the homebrew of postgresql and everything was fine after that. Then I messed around a bit with the the libpq.dylib link in /usr/lib so that an application would link to the brew installed version rather than the OS-installed version. Somehow I managed to break my install while doing this in such a way that any call to psql gives the following error:
>psql
psql: invalid connection option "client_encoding"
reinstalling postgresql with 'brew remove postgresql' and another 'brew install postgresql' doesn't seem to help (same error). I've also relinked /usr/lib/libpq.dylib to be /usr/lib/libpq.5.dylib, which is what I believe it was before.
Also, a potentially related problem is that my postgres server doesn't seem to want to shut down:
>pg_ctl -D /usr/local/var/postgres stop -s -m fast
pg_ctl: server does not shut down
Anyone have any clues as to what is wrong? Alternatively, how would I completely uninstall and reinstall the postgres server and client?
Try /usr/local/bin/psql. If that doesn't work, take a look at which psql.
Lion comes with a installation of postgresql running, and you might be using the stock psql instead of the brew psql.
Or that one might be running, and using the brew psql to connect to the Lion postgres instance.
Verify that /usr/local/bin is before /usr/bin in $PATH. Check echo $PATH.
Fix that worked for me:
if you use pgAdmin:
show server_encoding;
-bash-4.1$ export PGCLIENTENCODING='UTF8'
-bash-4.1$ psql
psql (9.3.3)
Type "help" for help.
postgres=# \l
...
put var in .profile or .bashrc
If you installed postgresql via homebrew:
brew update
brew doctor
Unexpected dylibs:
/usr/local/lib/libpq.5.dylib
Unexpected .la files:
/usr/local/lib/psqlodbcw.la
brew upgrade postgresql
Error: The brew link step did not complete successfully
brew link --overwrite postgresql
Then you should be fine to run the psql command.
if you've brew doctor'd and already have the latest version of postgres, run
brew unlink postgresql && brew link postgresql
then
brew link --overwrite postgresql
