This commit reverts 137805f89 as well as the associated commits 015e88942, 5306df283, and 68d704edb. We found multiple bugs in this feature, and there was concern about possible planner slowdown (though to be fair, exhibiting a very large slowdown proved difficult). The way forward requires a considerable rewrite, which may or may not be possible to accomplish in time for beta2. In my judgment reviewing the rewrite will be easier to accomplish starting from a clean slate, so let's temporarily revert what's there now. This also leaves us in a safe state if it turns out to be necessary to postpone the rewrite to the next development cycle. Discussion: <20160429102531.GA13701@huehner.biz>
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".
