Обсуждение: Adapting existing extensions to use CREATE EXTENSION
Hi folks, I've been looking at converting my existing "debversion" datatype extension to use the proper "CREATE EXTENSION" facility for 9.1, while also being backward compatible with 8.4 and 9.0. My initial work on the conversion is here: http://people.debian.org/~rleigh/postgresql-debversion_1.0.5.orig.tar.gz (this is based upon looking at how citext handles it plus the documentation and information at pgxn.org) Note that it uses autoconf/make rather than relying on PGXS. Extension support is disabled with --disable-extension. When disabled, it still installs a compatibility script in contrib/ to allow existing scripts to function (but it just wraps CREATE EXTENSION rather than doing everything by hand). I was wondering if anyone could possibly look it over to see if I'm missing anything, or doing anything stupid that I shouldn't in the new order of things. I'll release it and make it available on PGXN once I'm happy it's OK. Many thanks, Roger -- .''`.

I've been doing the same exercise with pgfincore recently, and will probably do some more of it later. You can look at those links for the time being: http://tapoueh.org/blog/2011/06/29-multi-version-support-for-extensions.html https://github.com/klando/pgfincore/tree/master/debian http://packages.debian.org/sid/postgresql-9.0-pgfincore Regards, -- Dimitri Fontaine http://2ndQuadrant.fr PostgreSQL : Expertise, Formation et Support

I did get everything working eventually--it's now available on http://pgxn.org/dist/debversion/ Not yet available in Debian due to dropping 8.4 compatibility; it'll go in once 9.1 is in unstable.
