I couldn't say exactly why, though.
Ok, here's a new version that handles row-level triggers with transition tables on any child table. The regression tests show partition and inheritance examples of that. To be clear about what this does: 1. If you attach a row-level trigger with transition tables to any partition, it will see transition tuples from all partitions that were modified by the same statement. 2. If you attach a row-level trigger with transition tables to any inheritance child, it will see transition tuples from all tables in the inheritance hierarchy at or below the directly named table that were modified by the same statement, sliced so that they appear as tuples from the directly named table.
