Two small issues here. First, your second call to
deleteDependencyRecordsFor did nothing, because your first call deleted
all the dependency records. I changed that to two
deleteDependencyRecordsForClass() calls, that actually do what you
intended.
The other is that instead of deleting each trigger, we can accumulate
them to delete with a single performMultipleDeletions call; this also
means we get to do CommandCounterIncrement just once.
v6 fixes those things and AFAICS is ready to push.
I haven't reviewed your 0002 carefully, but (as inventor of the "TABLE
t" marker for FK constraints) I agree with Amit that we should imitate
that instead of coming up with a new way to show it.
