This really depends on what data is actually in that field and if you need it to be exact. If the field actually contains integers and always will, then using an integer type field is *much* more efficient, either 'integer' if the values will always be less than 2B, or 'bigint' if it'll be larger. If the field actually contains floating point and can be inexact, then using 'real' or 'float8' will be more efficient than numeric. If the field needs to be exact (eg: monetary fields), then using numeric(10,3) is correct. I strongly recommend considering the data that goes into the field when making this decision- there really is no 'one size fits all' when going from number to numeric. Thanks, Stephen
