The regression test suite includes a table called "tab_core_types" that has one attribute based on the type "aclitem". Keeping this attribute as-is causes hard failures when running pg_upgrade with an origin on ~15. This commit updates upgrade_adapt.sql to automatically detect the tables with such attributes and switch them to text so as pg_upgrade is able to go through its run. This does not provide the same detection coverage as pg_upgrade, where we are able to find out aclitems used in arrays, domains or even composite types, but this is (I guess) enough for most things like an instance that had installcheck run on before the upgrade with a dump generated from it. Note that the buildfarm code has taken the simplest approach of just dropping "tab_core_types", so what we have here is more modular. Author: Anton A.
