Tom Lane	1173344e74	Adjust WAL code so that checkpoints truncate the xlog at the previous ... checkpoint's redo pointer, not its undo pointer, per discussion in pghackers a few days ago. No point in hanging onto undo information until we have the ability to do something with it --- and this solves a rather large problem with log space for long-running transactions. Also, change all calls of write() to detect the case where write returned a count less than requested, but failed to set errno. Presume that this situation indicates ENOSPC, and give the appropriate error message, rather than a random message associated with the previous value of errno.	2001-06-06 17:07:46 +00:00

Tom Lane	4eb5e27a28	Resetting the XLOG can't include rewinding it to logical position zero, ... because we need page LSNs stored in the main database to be less than the current XLOG position. Hence, generate the new XLOG segment at last old segment number plus one.	2001-03-16 05:08:39 +00:00
Tom Lane	eeaf3fc3a1	First cut at XLOG file reset utility. ... Could do with more testing, but it works in the simple cases.	2001-03-14 00:57:43 +00:00
