[HACKERS] Releasing an alpha for CF2
Hackers, I'd really like us to release an alpha version based on the finished CF2. There have been a number of major features added to PostgreSQL prior to this CF -- including Haas's performance improvements and range types -- which we really want at least some users to test early. Would it be possible to do an alpha release? -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

People trying range types are likely to try indexes on them. GiST on range types implementation in head have some limitations: 1) Full index scan for column @ const case. 2) Absence of selectivity estimation functions for , @, @ cause no GiST index usage until turning enable_seqscan to off. IMHO, it would be nice to release alpha version with range types without these limitations. I'm going to finish my patch for GiST on range types in couple of days. Concerning selectivity estimation, possible solution is to create some constant estimations with lower selectivity, which make planner use corresponding index by default (like we've for geometric datatypes). -- With best regards, Alexander Korotkov.

Alexander, People trying range types are likely to try indexes on them. GiST on range types implementation in head have some limitations: ... it's an alpha. There will always be one more patch. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Would it be possible to do an alpha release? Well, we discussed this not long ago, and the conclusion was that we could do an alpha release if and when someone was willing to write release notes. I suggested that it would make sense to do our first alpha after CF3, and that's still pretty much how I feel about it. If we're lucky, maybe we can twist Bruce's arm into doing it. Regardless, I don't think there's much time in trying to squeeze it into the week remaining before CF3, though; anything we write now will be obsolete almost as soon as it's written. An interesting question is this: What fraction of what is ultimately going to end up in this release is done now, or what fraction will be done by the end of CF3? Last time around, all the major features kind of fell on our head in January. But some of those - like SSI and sync rep - were things that we knew to be coming long in advance. I know various people are working on patches to do various things, but the only outstanding thing that sticks out in my mind as an outstanding big feature patch is Alvaro's work on foreign key locks. I'm sure there must be others... but I'm not sure how many. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

That's already approaching 3000 lines of code and he's still going on it. I've been sniffing around recently looking for troublesome patches, under the assumption I'll be running the CF next week, and those two are the ones I've been most concerned about. -- Greg Smith 2ndQuadrant USg...@2ndquadrant.com Baltimore, MD PostgreSQL Training, Services, and 24x7 Support www.2ndQuadrant.us -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
