These flags should be independent: in particular an index AM should be able to say that it supports include columns without necessarily supporting multiple key columns. The included-columns patch got this wrong, possibly aided by the fact that it didn't bother to update the documentation. While here, clarify some text about amcanreturn, which was a little vague about what should happen when amcanreturn reports that only some of the index columns are returnable. Noted while reviewing the SP-GiST included-columns patch, which quite incorrectly (and unsafely) changed SP-GiST to claim amcanmulticol = true as a workaround for this bug. Backpatch to v11 where included columns were introduced. |
