index file's growing big

Hi,

 I wrote a web+commandline based package with PostgreSQL database backend.
My problem is that as time goes by the index file grows to a huge size
[80Mb]. If I dump and then reload it the database in question I'll get the
very same data with a quite small index file. So, there's no inconsistency
or corrupt database, but it's still annoying that I must handle manually.
 What I think is tha the command-line app I wrote for populating the
database uses some wrong strategy, I mean there's no erroneous SQL phares,
just may be it uses wrong tactics that's why it grows the index file to a
quite big size.

 Any ideas?
