How to Disconnect from a database and go back to the default database in PostgreSQL?

Question

I'm using PostgreSql version :

postgres=# select version();                            version -------------------------------------------------------------  PostgreSQL 9.2.4, compiled by Visual C++ build 1600, 64-bit (1 row) 

i had connected to a database from postgres=# to newdb=#.... Now i'm in newdb=# Database i want to disconnect it and go back to postgres=# database ....

How to do this ?

I have tried with disconnect newdb;

but its giving erroe as::

postgres=# create database newdb; CREATE DATABASE postgres=# \c newdb; WARNING: Console code page (437) differs from Windows code page (1252)          8-bit characters might not work correctly. See psql reference          page "Notes for Windows users" for details. You are now connected to database "newdb" as user "postgres". newdb=# disconnect newdb; ERROR:  syntax error at or near "disconnect" LINE 1: disconnect newdb;         ^ newdb=# 

it isnt working is there any other way to do this or am i wrong in anything!!

Answer 1

It's easy, just look the example.

--my databases

postgres=# \l                                List of databases    Name    |  Owner   | Encoding | Collate | Ctype |     Access privileges      -----------+----------+----------+---------+-------+---------------------------  francs    | postgres | UTF8     | C       | C     | =Tc/postgres             +            |          |          |         |       | postgres=CTc/postgres    +            |          |          |         |       | francs=C*T*c*/postgres   +            |          |          |         |       | select_only=c/francs  postgres  | postgres | UTF8     | C       | C     |   source_db | postgres | UTF8     | C       | C     | =Tc/postgres             +            |          |          |         |       | postgres=CTc/postgres    +            |          |          |         |       | source_db=C*T*c*/postgres  template0 | postgres | UTF8     | C       | C     | =c/postgres              +            |          |          |         |       | postgres=CTc/postgres  template1 | postgres | UTF8     | C       | C     | =c/postgres              +            |          |          |         |       | postgres=CTc/postgres (5 rows) 

--switch to db francs as role francs

postgres=# \c francs francs You are now connected to database "francs" as user "francs". 

--swith to db postgres as role postgres

francs=> \c postgres postgres  You are now connected to database "postgres" as user "postgres". postgres=#  

--disconnect from db

postgres=# \q
