Hi Team,
I am using PostgreSQL 9.2.3 in Windows platform. I have created two databases in it. Now I want to refer the tables across the databases. Meaning would like to create Database link. Can anyone guide me on how to create a DB link?
 
Thanks and Regards

1 – why two databases?  Couldn’t you have just created two separate SCHEMAS?

2 – if you insist on two separate databases:   http://www.postgresql.org/docs/9.2/static/dblink.html

You can use db_link, see
http://www.postgresql.org/docs/9.2/interactive/dblink.html.

9.3 contains more:
http://www.postgresql.org/docs/9.3/interactive/postgres-fdw.html

But in general: don't use different databases if you need a
cross-database-connection. You can use Schemas instead:
http://www.postgresql.org/docs/9.2/static/ddl-schemas.html
