Ignore quals for unknown relation in resolve_quals#314
Open
Conversation
if the RESOLVE_ATTNAME query doesn't find an attribute name for a given relation oid and attribute number, it likely means that the table has been dropped since the underlying snapshot time. We could maybe try to find it in the catalog snapshot, but if the table doesn't exist anymore there is not point trying to do so as resolve_quals is only used to for hypothetical indexe which aren't needed for a table that doesn't exist anymore.
