I may be implementing a database at a customer's site that would
ideally run administration free for a year or so -- or at least
be able to have scripts detect proactively if they'd need to call
us for support before the system starts behaving poorly.
Is there a way to parse the output of "vacuum" to tell me
if my fsm settings aren't big enough to keep up, and or
indicate a need to vacuum more frequently?
Or am I better off looking at something else? Like perhaps
log_min_duration_statement and tell them to call us if
we see statements getting slow for any reason?
