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.

I found \c databasename by searching the Internet, but its runs only on psql. When I try it from the PostgreSQL query editor I get a syntax error.

I have to change the database by pgscripting. Does anyone know how to do it?

When you get a connection to PostgreSQL it is always to a particular database. To access a different database, you must get a new connection.

Using \c in psql closes the old connection and acquires a new one, using the specified database and/or credentials. You get a whole new back-end process and everything.

Thanks kgrittn for your valuable guidance.Can you tell me how I can make new connection to database and close previous by using pgscript query? – user1358896 Apr 27 '12 at 6:41
I'm not familiar with pgscript. If that's a language in which you write functions, the answer is that it can't be done. Maybe you should consider putting tables in different schemas instead of different databases? – kgrittn Apr 27 '12 at 12:40
Thanks.can we write simple query to change database???How? – user1358896 Apr 27 '12 at 13:39
A query can't change the database in PostgreSQL. – kgrittn Apr 28 '12 at 1:04

If I'm not mistaken, databases in MySQL are more akin to schemas in PostgreSQL -- you can switch between those, but DBs in PostgreSQL are a whole different ballgame. – Mark May 10 '12 at 3:40
