pgsql: Fix autovacuum cancellation.

Fix autovacuum cancellation.

The problem is caused by me (Andres) having ProcSleep() look at the
wrong PGPROC entry in 5788e258bb2.

Unfortunately it seems hard to write a reliable test for autovacuum
cancellations. Perhaps somebody will come up with a good approach, but
it seems worth fixing the issue even without a test.
