Hi Ed,
> Question: is it safe to insert/update/delete during VACUUM?
We have done a stress test on FreeBSD 2.2.7 with PG 6.4.3 and
6.5.2 with 2 processes in parallel: the first runs VACUUM VERBOSE
in a loop and the second does INSERT/UPDATE/DELETE's.
The database crashed after <5 mins, with different errors (not
only "duplicate tuples").
Howto VACUUM an online database?
