Hm ... the only argument I can really make against that is that there'll be no way to move such a table into shared memory; but there's probably little hope of that anyway, given points made upthread. The bitmapset manipulations are a bit tricky but solvable, and I agree there's something to be said for not tying this stuff so closely to the mechanism for relfilenode recycling. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
