pgsql: Add more tests with triggers on partitions for logical replicati

Add more tests with triggers on partitions for logical replication

The tuple routing logic used by a logical replication worker can fire
triggers on relations part of a partition tree, but there was no test
coverage in this area.  The existing script 003_constraints.pl included
something, but nothing when a tuple is applied across partitioned tables
on a subscriber.
