Hello all,

testing 8.3b3, i found out an interesting thing:

we have some plpgsql functions which use quote_literal() regardless of
the data type. With Beta 3 this does not work anymore[1].

Given the fact, that some functions do a lot of work, you (or at least
we) don't want to look, if the data you just moving around is from type
integer, text or something else. So in the past we just quoted
everything which worked fine.

I can understand, that enforcing a strict type checking is a fine
thing. But given the fact, that PG did a lot of implicit typecasting in
the past, removing this is not a real world solution. This will surely
prevent some more people from upgrading to 8.3 because the previous
fine-working applications will stop working on 8.3.

A quote_literal() which can cope with any data type, maybe combined
with a warning, would be a better way for a smooth upgrade.


Kind regards
