Since tuple-routing implicitly checks the partitioning constraints at least for the levels of the partitioning hierarchy it traverses, there's normally no need to revalidate the partitioning constraint after performing tuple routing. However, if there's a BEFORE trigger on the target partition, it could modify the tuple, causing the partitioning constraint to be violated. Catch that case. Also, instead of checking the root table's partition constraint after tuple-routing, check it beforehand. Otherwise, the rules for when the partitioning constraint gets checked get too complicated, because you sometimes have to check part of the constraint but not all of it. This effectively reverts commit 39162b2030fb0a35a6bb28dc636b5a71b8df8d1c in favor of a different approach altogether. Report by me. Initial debugging by Jeevan Ladhe. Patch by Amit Langote, reviewed by me. Discussion: http://postgr.es/m/CA+Tgmoa9DTgeVOqopieV8d1QRpddmP65aCdxyjdYDoEO5pS5KA@mail.gmail.com
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".
