minor error message inconsistency in make_pathkey_from_sortinfo

hi.

in make_pathkey_from_sortinfo

equality_op = get_opfamily_member(opfamily,
opcintype,
opcintype,
BTEqualStrategyNumber);
if (!OidIsValid(equality_op)) /* shouldn't happen */
elog(ERROR, "missing operator %d(%u,%u) in opfamily %u",
BTEqualStrategyNumber, opcintype, opcintype, opfamily);

the error message seems not right?

maybe
if (!OidIsValid(equality_op)) /* shouldn't happen */
elog(ERROR, "missing operator =(%u,%u) in opfamily %u",opcintype,
opcintype, opfamily);

or

if (!OidIsValid(equality_op)) /* shouldn't happen */
elog(ERROR, "missing equality operator for type %u in opfamily
%u",opcintype, opcintype, opfamily);
