At long last, here is version 1.1.5, which now supports PostgreSQL version 8.1. This has been run thru the Release Checklist There are two tarballs: slony1-1.1.5.tar.bz2 and prebuilt docs: slony1-docs-1.1.5-docs.tar.bz2 http://developer.postgresql.org/~wieck/slony1/download/slony1-1.1.5.tar.bz2 http://developer.postgresql.org/~wieck/slony1/download/slony1-1.1.5-docs.tar.bz2 The sources include the "new generation" test scripts, which make running a set of tests easier; see tests/README for more details. There are a few pointedly tasty improvements in store: 1. Compatibility with 8.1. There was a sort of "interlock" that abused pg_listener in order to make sure that each node was being managed by one and only one slon process. Functionality of Async_Unlisten() changed in 8.1, so we had to change strategy to use a new custom table to manage this. 2. Improved SUBSCRIBE SET performance. Indices are temporarily detached during the COPY statements, and then reattached and reindexed, which, in principle, should mean that subscribing a set should even be a bit faster than restoring from pg_dump (with Slony-I all the indices are regenerated together, so there should be benefits from the data already being in cache). 3. The New Generation test scripts have been added in, which should make it easier to run tests. 4. TRUNCATE is used to clear out tables at subscription time, if possible. 5. Man pages for slon, slonik, as well as all the slonik commands can now be generated. (It's unclear if this will necessarily be widely packaged straight off.) 6. There is official Debian packaging under way, in the "experimental" area. 7. A fairly large number of minor bugs that have been reported have been fixed. -- let name="cbbrowne" and tld="cbbrowne.com" in name ^ "@" ^ tld;; http://www3.sympatico.ca/cbbrowne/slony.html "...Unix, MS-DOS, and Windows NT (also known as the Good, the Bad, and the Ugly)." -- Matt Welsh
