我已经创建了用于覆盖内置（bytea，bytea）操作符的默认行为的操作符。这是允许的吗？我需要这个来覆盖数据库中自定义编码二进制数据的比较。

CREATE OPERATOR = (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    COMMUTATOR = =,
    NEGATOR = !=,
    PROCEDURE = fn_enc_eq,
    HASHES, MERGES
    );

CREATE OPERATOR != (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    COMMUTATOR = =,
    NEGATOR = !=,
    PROCEDURE = fn_enc_neq,
    HASHES, MERGES
    );

CREATE OPERATOR >= (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    PROCEDURE = fn_enc_gte,
    HASHES, MERGES
    );

CREATE OPERATOR > (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    PROCEDURE = fn_enc_gt,
    HASHES, MERGES
    );

CREATE OPERATOR <= (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    PROCEDURE = fn_enc_lte,
    HASHES, MERGES
    );

CREATE OPERATOR < (
    LEFTARG = bytea,
    RIGHTARG = bytea,
    PROCEDURE = fn_enc_lt,
    HASHES, MERGES
    );
