Hi,
I was wondering if PGSQL has a function similar to binary_checksum() of
MS SQL Server 2000. It is pretty handy when it comes to compare rows of
data instead of having to write long boolean expressions.
binary_checksum() takes a list of fields and it returns an integer value
which sumarize the row content.

Thanks,
Fed
