[ADMIN] ignoring data type

[Octavio]

Hello

I have migrate a application from a server with postgres 8.1 to another with 8.3
in the new server there are some page that doesn't work because seems to want 
to compare different data type

does anyone know if it is a version issue or there is something Im missing?

Thanks

Octavio
