Latest pg_autovacuum script

Hi,
I have updated the pg_autovacuum script with some bug fixes and
changes. Hope you find this useful.

-- This goes where all the other init scripts are located.
-- Can be placed at the top of /etc/rc.d/init.d/postgresql script or in the
/etc/sysconfig/pgsql/{name of script} e.g. postgresql, pg1, pg2
# Initialize pg_autovacuum defaults. Theo Galanakis 11/04/2005
PGAUTO_LOGFILE=/var/log/pg_autovacuum.{$PGPORT}.log
PGAUTO_SLEEP=600

--Include at the top of /etc/rc.d/init.d/postgresql
# pg_autovaccum Include script file. Theo Galanakis 11/04/2005
