I've just created a patch to return Python Decimals for Postgres Numeric 
types (Py < 2.4 where decimal does not exist still returns floats).

@D'Arcy: Shall I check this in? This creates some backward 
incompatibility, since PyGres returned only floats before.

What exactly did you do to get this error? Pygres should play nice with 
Decimals, the only problem is that it treats them are binary floats.
