After several months of intense development, and only almost two months of
testing and bug fixes, we are pleased to announce the release of
PostgreSQL v6.5 ...
Due to the huge number of changes and improvements made in this last
development cycle, it is highly recommended that you scan through the
HISTORY file, but a few of the major changes/improvements are:
Multi-version concurrency control(MVCC)
This removes our old table-level locking, and replaces it with a
locking system that is superior to most commercial database systems.
Hot backups from pg_dump
New SQL features
We now have CASE, INTERSECT, and EXCEPT statement support. We have
new LIMIT/OFFSET, SET TRANSACTION ISOLATION LEVEL, SELECT ... FOR
UPDATE, and an improved LOCK TABLE command.
We continue to expand our port list, this time including WinNT/ix86
and SpeedUps to several key areas within the system, to improve
performance...as well as improved resource utilitization enhancements.
This new release of PostgreSQL is available via:
