That's fairly unusual --- I can't think of any places where the
postmaster will exit without printing *some* complaint.

Shouldn't there be an & or something in there? Seems like that will
leave the su command blocked waiting for the postmaster to exit,
which of course it should not.

That won't tell you anything --- the trace will only trace what "su" does.
Better to su to pgsql and ktrace the postmaster directly.
