“use database_name” command in PostgreSQL

Question

I am beginner to PostgreSQL.

I want to connect to another database from the query editor of Postgres - like the USE command of MySQL or MS SQL Server. <

Answer 1

The basic problem while migrating from MySQL I faced was, I thought of the term database to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin, the result would not be as expected. As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.

For this, we can use the SET search_path command. This does switch the current schema to the specified schema name for the current session.

example:

SET search_path = different_schema_name;

This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf file.
