Make that "before".
I frankly suspect pilot error here. Triggers do not simply disappear.
If you did have crash-induced corruption leading to loss of some rows
in pg_trigger, it would be exceedingly obvious because *no* operations
on the affected tables would work --- relcache would complain about the
fact that pg_class.reltriggers didn't match the number of rows in
pg_trigger. I think the missing triggers must have been removed or
disabled deliberately. (Which is not to say that it couldn't have been
a software bug, but you're barking up the wrong tree to blame it on a
crash.)
Did all the triggers of the affected tables disappear, or only some
of them?
regards, tom lane
