Great, this is exactly what I think it needs. Meanwhile, I was checking out
http://www.postgresql.org/docs/7.3/static/sql-reindex.html
Which suggests I might be able to do a drop/add on each index with the
database 'live'.
However, the DROP INDEX command was taking an awfully long time to complete
and it hung my app in the mean time. Does anyone know if the DROP INDEX
causes an exclusive lock, or is it just a lengthy process?

Will do. Meanwhile I'm stuck supporting older 7.x versions, so I'm still
looking for a solution for them.
Thanks!
