NUMERIC and arithmetics

Hello,

in PG 7.1.x the NUMERIC data type makes some trouble with arithmetic and comparison
operators:

    delete from produkt where preis > 3.00;

yields

    ERROR:  Unable to identify an operator '>' for types 'numeric' and 'float8'

preis is typed NUMERIC(8,2). Strangely, "preis > 3" works.

Is this fixed in version 7.2?

Thanks,

Christoph Dalitz
