I don't really see a strong reason to keep it runable as a standalone
except that I thought that was what was decided in previous discussion
on hackers.  

Unfortunately, I can't find the thread anywhere on, when I search for "pg_autovacuum" it doesn't
return any hits more recent than Jan 2004, and I know there have been a
few pg_autovacuum related discussions since then so it seems like
something is broken.

I did understand Tom, but based on the hacker discussion I think the
"postmaster integration" will consist of the postmaster launching and
killing the pg_autovacuum standalone executable as required.  In that
sense, I don't think it matters if pg_autovacuum is located in src/bin
or src/backend/postmaster.

Is this form of integration something people would object to? If so, I
can fold it into the backend such that pg_autovacuum can no longer be
run from the command line.

Comments anyone?
