we are using postgresql 8.1.3 and wanted to enable autovacuuming for only

pg_autovacuum seems to allow to ignore only a particular table and not the
database since column vacrelid is OID from pg_class table Are there any
suggestions to accomplish this tasks?.
Currently there is no way to exclude entire databases from autovacuum.
IIRC in one of the original patches I had added a way to do it. It was
rejected however; it was argued that there was another mechanism to
disable it. I don't remember what it was though. The only possibility
that comes to mind is "ALTER DATABASE SET autovacuum TO off" but I don't
see why would it work.
I think the closest approximation of disabling autovacuum on a per
database basis is to connect to the database in question and perform:
update pg_autovacuum set enabled = 'false';
This will prevent autovacuum from vacuuming or analyzing any of the
tables in the database, but will still check for XID wraparound.
