No, for me. Do Informix, Oracle, etc use two words ?
What benefit of special "in-parser-error" word for user - in any case
user will read error message itself to understand what caused error.

Good question :)
Following your way
insert into X (an_int2_field) values (9999999999);
should cause ERROR message, but
insert into X (an_int2_field) select an_int4_field from Y;
should return ABORT message if value of some an_int4_field in Y is
greater than 32768.
