If you haven't done the usual general tuning on your server, that might
help. http://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server is
an introduction. If increasing maintainance_work_mem alone doesn't
help, I'd try increases to checkpoint_segments and then shared_buffers
next. Those are the three parameters mostly likely to speed that up.
The things already suggested in this thread are still valid though.
Needing to REINDEX suggests there may be a problem with your database
better addressed by running autovacuum more regularly.
