Maybe the Ora2Pg tool will help.

Data was sent to our company with PostgreSQL, but we are prohibited to use the tools of PostgreSQL , permitted the use of only Oracle.
How to migrate data from PostgreSQL to Oracle without using a third party application(they are also prohibited)? You can only use the tools of Oracle.
I found this article https://support.oracle.com/knowledge/Oracle%20Database%20Products/2220826_1.html but we don't have Support Identifier
We have one .sql file. It weighs 8 Gigabytes.
It looks like you have so many impediments in your company. Regarding Oracle's SQL Developer Migration Workbench, unfortunately it does not support the migration of PostgreSQL databases. However, the following 3rd-party software tools are available and may assist in migration, but I am afraid you cannot use them as you said that those products are forbidden:

Other options will only move the data from your Postgresql database to Oracle database, it means that you must have the DDLs of the tables before to run the import:
To move data only, you can generate a flat file of the the
PostgreSQL data and use Oracle SQL*Loader.
Another option to migrate data only is to use Oracle Database
Gateway for ODBC which requires an ODBC driver to connect to the
PostreSQL database, and copy each table over the network using
sqlplus "COPY" or "CREATE TABLE AS SELECT" commands via oracle
database link.
Also, Oracle has discussion forum for migrating non-oracle databases to Oracle.
http://www.oracle.com/technetwork/database/migration/third-party-093040.html
But, if you have only a sql file, you should look at it to see whether you have both DDLs ( create tables and indexes, etc ) and the data itself as insert statements. If so, you need to split it and treat the DDLs to convert the original data types to Oracle datatypes.
Is there a way to work with SQL Loader for a PostgreSQL database or is it for Oracle Databases only?
SQL*Loader is an Oracle utility that uses an oracle client/oracle call interface to talk to an Oracle Database ONLY.
I want to try TiDB and I am working on data migration. Is there any way of migrating data from DB2 or Oracle to TiDB?
If using OGG to sync data to TiDB, you should set global tidb_constraint_check_in_place = 1 to disable the lazy-constraint-check in TiDB.
To migrate all the data or migrate incrementally from DB2 or Oracle to TiDB, you can use one of the following solutions:
Use the official migration tool of Oracle, such as OGG, Gateway, CDC (Change Data Capture).
Develop a program for importing and exporting data.
Export Spool as text file, and import data using Load infile.
Use a third-party data migration tool.
Currently, it is recommended to use OGG.
Oracle SQL Developer will capture and convert your LUW DB2 database and create it in an existing Oracle Database as new schema(s). It will move the data for you too.

Is it possible to get a structure of a derby database so it is saved in a form of an sql script that I can run and it would recreate the database along with the data in it?
The dblook tool (http://db.apache.org/derby/docs/10.8/tools/ctoolsdblook.html) will get the structure of the database and export it as a SQL script.
But it doesn't extract the data.
You could perhaps use the backup and restore utilities, but the format of a Derby backup is not a sql script.
The Apache 'ddlutils' tool can extract and move the data, I believe. See: http://db.apache.org/derby/integrate/db_ddlutils.html
and

I have a Microsoft SQL Server database(tables, relationships and data).
But now I want an exact same copy of this database in Oracle.
I was thinking there may be some sort of a tool or converter that could generate Oracle sql scripts that I could run to create and populate my new Oracle database.
Is this kind of thing possible?
And how can I achieve this ?
Your best bet is to use a DB modelling tool which can reverse engineer your SQL Server database and then generate a script to recreate it in Oracle.
DB Designer Fork can do this for you and is Open Source.
