Always use quotes regardless of a column value (numeric vs string), e.g. '$value'. Postgres is smart enough to convert quoted numbers to numeric values. I am not sure if there is overhead associated with this, but the only other option is to analyze the column type and act accordingly. Keary Suska Esoteritech, Inc.
