Bugzilla Bug 194701

After installing the dev-db/postgresql ebuild, the installation log contains a
hint to enable autovacuum in ${ROOT}/etc/postgresql/postgresql.conf. However,
the configuration file resides in /var/lib/postgresql/data/postgresql.conf. So
this should be probably reflected in the ebuild as well.

Reproducible: Always

Steps to Reproduce:
1. install dev-db/postgresql
2. fail to find the configuration file in the stated location
3. after a time span depending on prior postgresql experience, locate it in the
data directory of the postgresql daemon

Actual Results:  
I decided to disregard the information from the ebuild and successfully enabled
autovacuum in /var/lib/postgresql/data/postgresql.conf, restarted the
postgresql daemon and verified the success of this action by doing a "show
autovacuum;" at the psql prompt.

Expected Results:  
It should have displayed the correct file location on successful installation.

I just saw that I forgot to supply the ebuild version. It's 8.2.4-r1.

Done. Thanks.
