postgres home directory - Mailing list pgsql-novice

I have postgres running under RedHat 7.1 and was looking
for the postgres file structure.  Its supposed to start
at
/usr/local/pgsql  with /bin, /data, /data/base... under
it.  psql is supposed to be in the prsql directory -
well
it is in /usr/local with no pgsql directory.

What commands might I use to find the rest of the
postgres
files?
