In fact, with a bit of experimentation I see the same error message:

regression=# select to_number('12345', '99999');to_number
-----------    12345
(1 row)

regression=# select to_number('1234 ', '99999');to_number
-----------     1234
(1 row)

regression=# select to_number(' 1234', '99999');to_number
-----------     1234
(1 row)

regression=# select to_number('     ', '99999');
ERROR:  invalid input syntax for type numeric: " "
regression=# select to_number('zzzzz', '99999');
ERROR:  invalid input syntax for type numeric: " "
regression=#

The error message's report of the input string seems a tad misleading,
especially in the last case.  (Karel, is this fixable?)  But anyway,
it sure looks like the problem is bad input data.
