Re: Connecting 2 databases within the same instance

[Ron <ronljohnsonjr@xxxxxxxxx>]

    Google is your friend.  Searching for "postgresql dblink" and
    "postgresql fdw" take you right to the documentation:
    https://www.postgresql.org/docs/15/dblink.html
    https://www.postgresql.org/docs/current/postgres-fdw.html
    
    DB Link is much older, while FDW has better syntax and is usually
    faster:
    "
    The functionality provided by this
      module overlaps substantially with the functionality of the older dblink module. But postgres_fdw provides more transparent
      and standards-compliant syntax for accessing remote tables, and
      can give better performance in many cases.

Hi,

Are you saying that Db Link is existing in the Postgress or just referring to FDW ?

I think any of the two contrib module dblink and/or postgres_fdw could help

Hello,

 

 I have one instance and two database within it. What is the simplest approach which I can adopt to connect these 2 database to one another.

I want to have the ability to connect to any table. For example database link in Oracle databases. How can I deploy this gracefully?

 

Thanks,

Sarwar
