i'm running mnogosearch along with pgsql-current. and performance have
been just terrible to get results back on a resonable time. i couldn't
figure out so i check my ./configure flags. and there it was
--enable-debug. after sending my email to the list, i recompiled w/o debug
and now i can get my results back from a query in less than 2
seconds. before it was 59 secs if it returned at all. size of postgres
went down from 11.5 MB to a little less than 3mb. overall things seem
faster for inserts and selects for newly started backends too.
