RE: Question on postgresql.conf

Thanks for your reply.

I can start the database like this: pg_ctl start -D /hostname/postgres/data -l /hostname/postgres/log

My data directory has the following file:
postgres.cnf

Content of the postgres.cnf contains only 1 line:
include /nfs/global/postgres-<hostname>.cnf

Question:
Can <hostname> be a variable like `hostname` derived from Unix shell or I have to hardcode the name of the host like " include /nfs/global/postgres-host123.cnf

What I'd do is make each data directory's postgresql.conf contain just this:

include /nfs/global/postgres-<hostname>.cnf

and then just start the postmaster without any weird switches.
In this way you will avoid breaking PG-specific tools that expect to find the config file at its standard location.
