dropping and recreating indexes vs. reindexing

hello all,

I used to drop and recreate all user indexes once every night.
I noticed that this led to an increase of performance...

Today, using postgres-7.2.1, I wonder if this still has
benefits, or if I should better use "reindex" or if I
don't have to bother about reindexing at all ?

any information appreciated,
