Add indisreplident to fields refreshed by RelationReloadIndexInfo()
RelationReloadIndexInfo() is a fast-path used for index reloads in the relation cache, and it has always forgotten about updating indisreplident, which is something that would happen after an index is selected for a replica identity. This can lead to incorrect cache information provided when executing a command in a transaction context that updates indisreplident. None of the code paths currently on HEAD that need to check upon pg_index.indisreplident fetch its value from the relation cache, always relying on a fresh copy on the syscache. Unfortunately, this may not be the case of out-of-core code, that could see out-of-date value.
