ALTER_OPERATOR_CLASS(7pg17)

💅 ALTER OPERATOR CLASS 💅

ok so bestie, we're in the PostgreSQL 17.11 Documentation girlies today, and this page is all about ALTER OPERATOR CLASS — that's "alter operator class", and yes it does exactly what it says on the tin: change the definition of an operator class. iconic behavior honestly. 🎀

---

✨ SYNOPSIS ✨

three whole moods, pick your fighter:

ALTER OPERATOR CLASS name USING index_method
    RENAME TO new_name

ALTER OPERATOR CLASS name USING index_method
    OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }

ALTER OPERATOR CLASS name USING index_method
    SET SCHEMA new_schema

---

🌸 DESCRIPTION 🌸

ALTER OPERATOR CLASS changes the definition of an operator class. that's it, that's the whole vibe. 🦋

ok but the fine print is where it gets real: you must own the operator class to use ALTER OPERATOR CLASS. no ownership, no entry, iykyk. and if you're trying to alter the owner, you gotta be able to SET ROLE to the new owning role, and that role must have CREATE privilege on the operator class's schema. yes both things. it's giving "gatekeeping" but it's for a reason:

these restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the operator class. so like, no sneaky backdoor privilege stuff. periodt. 🚫

however (and this is the main character exception ✨), a superuser can alter ownership of any operator class anyway. they just can. slay.

💖 PARAMETERS 💖

• name — the name of an existing operator class, and it can be optionally schema-qualified. like, dress it up, add the schema, it's fine. 👑
• index_method — the name of the index method this operator class is for. gotta say which method, bestie, it's not a mind reader.
• new_name — the new name of the operator class. glow-up name. rebrand era. 🦋
• new_owner — the new owner of the operator class. handing over the crown. 🎀
• new_schema — the new schema for the operator class. moving houses. ✨

---

🌈 COMPATIBILITY 🌈

big mood: there is no ALTER OPERATOR CLASS statement in the SQL standard. so, like, standard says nothing, PostgreSQL says we ball. 💀
