We now disallow having triggers with both transition tables and ON INSERT OR UPDATE (which was a PG extension to the spec anyway), because in this case it's not at all clear how the transition tables should work for an INSERT ... ON CONFLICT query. Separate ON INSERT and ON UPDATE triggers with transition tables are allowed, and the transition tables for these reflect only the inserted and only the updated tuples respectively.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
