Tom Lane	e26b0abda3	Arrange to fsync two-phase-commit state files only during checkpoints; ... given reasonably short lifespans for prepared transactions, this should mean that only a small minority of state files ever need to be fsynced at all. Per discussion with Heikki Linnakangas.	2005-06-19 20:00:39 +00:00
Tom Lane	a8d1075f27	Add a time-of-preparation column to the pg_prepared_xacts view, per an ... old suggestion by Oliver Jowett. Also, add a transaction column to the pg_locks view to show the xid of each transaction holding or awaiting locks; this allows prepared transactions to be properly associated with the locks they own. There was already a column named 'transaction', and I chose to rename it to 'transactionid' --- since this column is new in the current devel cycle there should be no backwards compatibility issue to worry about.	2005-06-18 19:33:42 +00:00
Tom Lane	66b098492e	Dept. of second thoughts: regular COMMIT deletes deletable files before ... releasing locks, so COMMIT PREPARED should too.	2005-06-18 05:21:09 +00:00
