My guess is you upgraded from a version prior to 8.3. In 8.3 many of the implied
casts where removed, so you probably have to go over your code and make the
corrections.
Go here for more detail:
http://www.postgresql.org/docs/8.4/interactive/release-8-3.html
SectionE.21.2.1. General
A temporary solution can be found here:

An important tip from the blog-
"The gist was, only restore the casts you need, not all of them."
