Thanks all,

Actually I am trying to setup a postgres failover using common setup.

I.e,
A postgres data directory is stored in central location.
Two postgres uses the same location 
If One postgres down and the other will start....

The problem is, If the postgres users in the two machines has different UID's then i need to change ownership of data directory every time -- which takes long time 
If din't change ownership of data directory then i am getting access denied errors ..

So if the both users have same UID's then there is no issue.

Hi All,

While installing postgres, a user named "postgres" will be automatically created.
What is the default UID for postgres user in linux ?

There isn't one. PostgreSQL isn't in charge of assigning user-names or passwords and the user under which it runs does not have to be postgres.

Many Linux distributions will create a "postgres" user with PostgreSQL is installed but the UID can vary depending on distribution and the order that services were installed. I just looked at a few of my machines and found UIDs of 114, 106, 107, 26, ... and a similar variation in GID.

Cheers,
Steve
