Tom Lane efcaf1e868 Some mop-up work for savepoints (nested transactions). Store a small ... number of active subtransaction XIDs in each backend's PGPROC entry, and use this to avoid expensive probes into pg_subtrans during TransactionIdIsInProgress. Extend EOXactCallback API to allow add-on modules to get control at subxact start/end. (This is deliberately not compatible with the former API, since any uses of that API probably need manual review anyway.) Add basic reference documentation for SAVEPOINT and related commands. Minor other cleanups to check off some of the open issues for subtransactions. Alvaro Herrera and Tom Lane.		2004-08-01 17:32:22 +00:00
