We allow INSERT and UPDATE commands to assign to the same column more than once, as long as the assignments are to subfields or elements rather than the whole column. However, this failed when the target column was a domain over array rather than plain array. Fix by teaching process_matched_tle() to look through CoerceToDomain nodes, and add relevant test cases. Also add a group of test cases exercising domains over array of composite. It's doubtless accidental that CREATE DOMAIN allows this case while not allowing straight domain over composite; but it does, so we'd better make sure we don't break it. (I could not find any documentation mentioning either side of that, so no doc changes.) It's been like this for a long time, so back-patch to all supported branches.

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".
