Okay, so after changing longitude/latitude to float4, and re-organizing the table a bit, I got the query down from about 8 minutes to 40 seconds. The details are in the gist comments: https://gist.github.com/ioquatix/bddda36d9e4ffaceb7a62d7b62259121 Now, just need to get performance another 2 orders of magnitude better. Can we make the index a bit more coarse grained, perhaps convert long/lat to integers or something, use a hilbert index, use a postgis index... ideas? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
