Agreed, that's a mistake. > Right. This maps with RELKIND_HAS_STORAGE().

Well, the patch replaces the switch on individual relkind values with if tests on RELKIND_HAS_FOO macros. I suppose we'd have Assert(RELKIND_HAS_STORAGE(relkind)); so the function would not even be called for partitioned indexes. (In a quick scan of 'git grep RelationGetNumberOfBlocks' I see nothing that would obviously call this function on a partitioned index.) -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/ "XML!"
