Crank up the error reporting verbosity.  For instance, in psql

regression=# select 'i'::integer;
ERROR:  invalid input syntax for integer: "i"
regression=# \set VERBOSITY verbose
regression=# select 'i'::integer;
ERROR:  22P02: invalid input syntax for integer: "i"
LOCATION:  pg_atoi, numutils.c:84
regression=#

A look in Appendix A of the manual shows that 22P02 is
INVALID TEXT REPRESENTATION
