Is your Lambda function in a VPC without a NAT gateway? Looks like it doesn't have an outbound internet connection since it doesn't have an IP address.
Try removing the Lambda from the VPC if you don't need to access VPC private resources.
Otherwise, it also looks like you need to access RDS from within the Lambda, so in that case, you should add a NAT gateway to your VPC.
Some useful resources:

I wanted to connect to postgresql database using connection string in form of
host=localhost user=x password=y dbname=z
this works fine when passed to psql
$ psql "host=localhost user=x password=y dbname=z"
and when passed to the PG gem
> PG.connect("host=localhost user=x password=y dbname=z")
however it fails when I try to pass it into sequel
> Sequel.postgres(constr)
Sequel::DatabaseConnectionError: PG::ConnectionBad: could not connect to server: No such file or directory
How can I make sequel connect to my database?
You could use a string with the connection information, for example:
conn_str = 'postgres://localhost/database_name?user=user&password=password'
DB = Sequel.connect(conn_str)
Check the Sequel's documentation of how to open connections with a hash
DB = Sequel.connect(
adapter: 'postgres',
host: 'localhost',
database: 'database_name',
user: 'database_user',
password: 'password'
)
Then you should be able to run:
DB[:table_name].where(:attribute => 5000..10000)
Or you could use the postgres method directly:
DB = Sequel.postgres('my_db', :user => 'user', :password => 'password', :host => 'localhost')
Check devhints open connection shortcuts
