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
