This is just a guess, increasing the parameters shared_buffers and sort_mem might help. For example if your table is about 1Gb in size then try shared_buffers=10000 and sort_mem=20000 ( you need an extra 100Mb ram for this ) Cheers Mark ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
