I'm currently reworking the patch so that things that need to be abstract per discussion are abstract, without enlarging the scope excessively. I'm working on an opclass implementation that can be used for "sortable" datatypes, so that it covers the datatypes it covers today (basically anything with a btree opclass). I don't intend to implement opclasses for any other type, but with the design I expect to have it should be possible to cover stuff like geometric types usefully. (I guess it will be possible to index arrays in a general way also, but I don't think it will be of any usefulness). Once I post that version, I will focus on reviewing other patches, and then maybe someone interested can try to implement other opclasses on top of it, to ensure that the API I propose is sensible or at least useful. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
