Tom Lane aa903cf07c Remove pg_vlock locking from VACUUM, allowing multiple VACUUMs to run in ... parallel --- and, not incidentally, removing a common reason for needing manual cleanup by the DB admin after a crash. Remove initial global delete of pg_statistics rows in VACUUM ANALYZE; this was not only bad for performance of other backends that had to run without stats for a while, but it was fundamentally broken because it was done outside any transaction. Surprising we didn't see more consequences of that. Detect attempt to run VACUUM inside a transaction block. Check for query cancel request before starting vacuum of each table. Clean up vacuum's private portal storage if vacuum is aborted.		1999-11-28 02:10:01 +00:00
