Andres Freund 89fd41b390 Fix and improve cache invalidation logic for logical decoding. ... There are basically three situations in which logical decoding needs to perform cache invalidation. During/After replaying a transaction with catalog changes, when skipping a uninteresting transaction that performed catalog changes and when erroring out while replaying a transaction. Unfortunately these three cases were all done slightly differently - partially because 8de3e410fa, which greatly simplifies matters, got committed in the midst of the development of logical decoding. The actually problematic case was when logical decoding skipped transaction commits (and thus processed invalidations). When used via the SQL interface cache invalidation could access the catalog - bad, because we didn't set up enough state to allow that correctly. It'd not be hard to setup sufficient state, but the simpler solution is to always perform cache invalidation outside a valid transaction. Also make the different cache invalidation cases look as similar as possible, to ease code review. This fixes the assertion failure reported by Antonin Houska in 53EE02D9.7040702@gmail.com. The presented testcase has been expanded into a regression test. Backpatch to 9.4, where logical decoding was introduced.		2014-11-13 20:34:31 +01:00
