Message-ID: <E1rnPXK-004zQW-FT@gemulon.postgresql.org> (raw)
Add TupleTableSlotOps.is_current_xact_tuple() method
This allows us to abstract how/whether table AM uses transaction identifiers.
A custom table AM can use a custom slot, which may not store xmin directly,
but determine the tuple belonging to the current transaction in the other way.
