It doesn't work correctly with your patch; see sample below.  Note the
caret is pointing to an entirely nonsensical position.  I'm not sure
about duplicating the libpq line-counting logic in the backend.

Also note i18n seems to be working well, except for the "In function"
header, "query", and the error level.  That seems easily fixable.

I remain unconvinced that this is the best possible output.

alvherre=# create function f() returns int language plpgsql as $$
begin select
var
from
foo; end; $$;
CREATE FUNCTION
alvherre=# check function f();                    CHECK FUNCTION
---------------------------------------------------------In function: 'f()'error:42P01:2:sentencia SQL:no existe la
