Heikki Linnakangas	8f9b9590d7	Handle duplicate XIDs in txid_snapshot. The proc array can contain duplicate XIDs, when a transaction is just being prepared for two-phase commit. To cope, remove any duplicates in txid_current_snapshot(). Also ignore duplicates in the input functions, so that if e.g. you have an old pg_dump file that already contains duplicates, it will be accepted. Report and fix by Jan Wieck. Backpatch to all supported versions.	2014-05-15 18:29:20 +03:00
Tom Lane	18e3fcc31e	Migrate the former contrib/txid module into core. This will make it easier for Slony and Skytools to depend on it. Per discussion.	2007-10-13 23:06:28 +00:00

Handle duplicate XIDs in txid_snapshot.

The proc array can contain duplicate XIDs, when a transaction is just being
prepared for two-phase commit. To cope, remove any duplicates in
txid_current_snapshot(). Also ignore duplicates in the input functions, so
that if e.g. you have an old pg_dump file that already contains duplicates,
it will be accepted.

Report and fix by Jan Wieck. Backpatch to all supported versions.
