Thread: Database Link between 2 PostgreSQL db

Hello,
Oracle has a concept of Database link, IE you can access data from a table in
different database, even if the database is in different host, using
something like

SELECT * FROM table@REMOTE_CONNECT;

Is there something similar in PostgreSQL? I would like to know if I can access
my data on a remote PostgreSQL server from a local PostgreSQL database.

Thank you in advance for any respond.

RDB

You can use dblink.

example:


> SELECT *

>       AS t1(proname name, prosrc text)
>     WHERE proname LIKE 'bytea%';
