ALTER TABLE commands in an extension script are added to an event trigger command list; but starting with commit b5810de3f4 they do so in a memory context that's too short-lived, so when execution ends and time comes to use the entries, they've already been freed. (This would also be a problem with ALTER TABLE commands in a multi-command query string, but these serendipitously end in PortalContext -- which probably explains why it took so long for this to be reported.) Fix by using the memory context specifically set for that, instead. Backpatch to 13, where the aforementioned commit appeared.

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".
