[csw-users] postgres 9.1 usage ?

[Gerard Henry]

hello all,
i'm trying to use postgres 9.1 from opencsw.
I'm a little bit loast with different configration files, in the past, i 
used:
postgresql.conf
pg_hba.conf


looking at CSWpostgresql91-server, i found:
/opt/csw/share/postgresql/91/pg_hba.conf.sample
/opt/csw/share/postgresql/91/pg_ident.conf.sample
/opt/csw/share/postgresql/91/pg_service.conf.sample
/opt/csw/share/postgresql/91/postgresql.conf.sample
/opt/csw/share/postgresql/91/recovery.conf.sample
and
/etc/opt/csw/postgresql-91.conf.CSW

it seems to me that /opt/csw/share/postgresql/91/postgresql.conf.sample 
has nothing to do with /etc/opt/csw/postgresql-91.conf.CSW ?
so, what's the best way to configure listen_addresses and users?
is it ok to copy /opt/csw/share/postgresql/91/pg_hba.conf.sample in 
/etc/opt/csw/ ?

thanks in advance,

gerard
