Are your FSM settings enough to keep track of the dead space you have?
I don't know. How do I check?
vacuum verbose;
Toward the bottom you will see something like:
...
1200 page slots are required to track all free space.
Current limits are: 453600 page slots, 1000 relations, using 2723 kB.
....
Make sure your current limits have a higher number than the page slots
required.
Cheers,

Am I correct in that this number will GROW over time? Or is what I see
right now (with everything running ok) all that the system
will ever need?
If the latter, then I'm WELL within limits and I guess I need to tune
the autovacuum parameters to be more aggressive; system views show it IS
being run.
