Tatsuo Ishii	8436f9a036	Add libpq new API lo_import_with_oid() which is similar to lo_import() ... except that lob's oid can be specified.	18 years ago
Bruce Momjian	2f2b58d642	Spit items: ... * Experiment with multi-threaded backend better I/O utilization This would allow a single query to make use of multiple I/O channels simultaneously. One idea is to create a background reader that can pre-fetch sequential and index scan pages needed by other backends. This could be expanded to allow concurrent reads from multiple devices in a partitioned table. * Experiment with multi-threaded backend better CPU utilization This would allow several CPUs to be used for a single query, such as for sorting or query execution.	18 years ago
Bruce Momjian	8426b5640e	Update TODO description: ... * Speed WAL recovery by allowing more than one page to be prefetched This should be done utilizing the same infrastructure used for prefetching in general to avoid introducing complex error-prone code in WAL replay.	18 years ago

Tom Lane	033eb1581b	Fix LISTEN/NOTIFY race condition reported by Laurent Birtz, by postponing ... pg_listener modifications commanded by LISTEN and UNLISTEN until the end of the current transaction. This allows us to hold the ExclusiveLock on pg_listener until after commit, with no greater risk of deadlock than there was before. Aside from fixing the race condition, this gets rid of a truly ugly kludge that was there before, namely having to ignore HeapTupleBeingUpdated failures during NOTIFY. There is a small potential incompatibility, which is that if a transaction issues LISTEN or UNLISTEN and then looks into pg_listener before committing, it won't see any resulting row insertion or deletion, where before it would have. It seems unlikely that anyone would be depending on that, though. This patch also disallows LISTEN and UNLISTEN inside a prepared transaction. That case had some pretty undesirable properties already, such as possibly allowing pg_listener entries to be made for PIDs no longer present, so disallowing it seems like a better idea than trying to maintain the behavior.	18 years ago
