oh, and vacuum is totally safe to be run concurrently with transactions,
the only negative impact is the performance impact of the additional IO
and CPU resources the VACUUM uses while active. Ditto REINDEX, it should
be safe, at most it will lock an index til that index is rebuilt..
with autovacuum, doing nightly vacuums and analyzes shouldn't be
neccessary...
