I was thinking we should make the partitioning decision FIRST, before
any triggers are fired, and then fire only those triggers relevant to
the selected partition.  If the BEFORE triggers on the partition
modify the tuple in a way that makes it incompatible with the table
constraints on that partition, the insert (or update) fails.

Firing triggers on more than one table is pretty substantially
incompatible with what we do elsewhere and I'm not clear what we get
in exchange.  What is the use case for this?
