The multi-argument form of pg_get_indexdef() failed to print anything when asked to print a single index column that is an included column rather than a key column. This seems an unintentional result of someone having tried to take a short-cut and use the attrsOnly flag for two different purposes. To fix, split said flag into two flags, attrsOnly which suppresses non-attribute info, and keysOnly which suppresses included columns. Add a test case using psql's \d command, which relies on that function. (It's mighty tempting at this point to replace pg_get_indexdef_worker's mess of boolean flag arguments with a single bitmask-of-flags argument, which would allow making the call sites much more self-documenting. But I refrained for the moment.) Discussion: https://postgr.es/m/21724.1531943735@sss.pgh.pa.us
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".
