I won't have access to the original testcase and server for a few days but I just redid some testing on a slower personal box of mine with a smaller(but similiar) testset and on that box I could not reproduce that issue. So the problem is either caused by the size of the table or somehow by the data itself :-(
We tested gin with 5 millions records (but not a wikipedia's text, but with blog records which is usually mush shorter) and index creation time was near 8 hours on Dual Xeon 3.2, but we didn't try GiST. In other hand, creating GiST index on 0.5 millions emails took about 12 hours.
That's why 7 minutes is very suspicious result. -- Teodor Sigaev E-mail: [EMAIL PROTECTED] WWW: http://www.sigaev.ru/ ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
