operator varchar = integer

Hey Group,

i know what all will say but i need to recreate the = operator for
datatypes varchar and integer in PostgreSQL 8.3.

Our Software Project has Millions of Lines and so it would be difficult
to check all queries and Datatypes. Also it works really fine and we all
know the risk of wrong auto casting.

Anyone knows the Syntax?

Thanks a lot for your great work.


Daniel.
