You can try using REINDEX instead of dropping and creating the index. It
takes an exclusive lock on the table (instead of a write-lock during CREATE
INDEX) so your application will have to wait during reindex, but maybe it is
faster... When you use the reindexdb script in the contrib dir you can even
put it in a crontab.
