I would split those triggers up, unless there's a good reason not to. 
If you have a bunch of huge "INSERT OR UPDATE OR DELETE" triggers, and
they all have a top-level switch that says "IF INSERTING ... IF
UPDATING ...", then it seems they'd be better off (cleaner) as
seperate triggers anyways.

The PK::Auto code for most backends will probably always be a bit
heuristic in nature, and there will probably always be odd cases that
it cannot figure out without hints from you.  I think perhaps the most
productive change to PK::Auto and friends would be to make it easier
and more obvious for you to override _get_autoinc_seq logic for your
particular database class as a whole (as opposed to per-table).

Just my $0.02,
