In that case, attached is a patch which locates the beginning of the
offending token more efficiently (per your suggestion of using
scanbuf). The new patch does the same as before:
template1=# select * frum pg_class;
ERROR: parser: parse error at or near "frum" at character 10
It also implement's Tom's suggestion:
template1=# select * from pg_class where\g
ERROR: parse: parse error at end of input
