Well, I guess that would be a good solution to the "queue table"
problem. The problem is that I can't deploy that patch on our production
systems without being fairly sure it won't corrupt any data... and I
can't rely on non-production testing either. Basically I'm waiting to
see Tom saying it will fly :-)
That patch is a step forward if it's deemed OK by the powers that be.
However, autovacuum would still need to be taught to handle simultaneous
vacuums. I suppose that in the interim, you could disable autovacuum
for the problematic queue table and have cron issue a manual vacuum
command for that table at the required frequency.
Anyone up for working on / testing / improving Hannu's patch? I think
it's beyond my skill set.
