Commit 6f6b99d13 stuck an INFO message into the fast path for checking partition constraints, for no very good reason except that it made it easy for the regression tests to verify that that path was taken. Assorted later patches did likewise, increasing the unsuppressable-chatter level from ALTER TABLE even more. This isn't good for the user experience, so let's drop these messages down to DEBUG1 where they belong. So as not to have a loss of test coverage, create a TAP test that runs the relevant queries with client_min_messages = DEBUG1 and greps for the expected messages. This testing method is a bit brute-force --- in particular, it duplicates the execution of a fair amount of the core create_table and alter_table tests. We experimented with other solutions, but running any significant amount of standard testing with client_min_messages = DEBUG1 seems to have a lot of output-stability pitfalls, cf commits bbb96c370 and 5655565c0. Possibly at some point we'll look into whether we can reduce the amount of test duplication. Backpatch into v12, because some of these messages are new in v12 and we don't really want to ship it that way.

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".
