ALTER_OPERATOR_CLASS(7pg16)

💅 ALTER OPERATOR CLASS 💅

okay so real talk, bestie — you're reading the ALTER OPERATOR CLASS(7) page from the PostgreSQL 16.15 Documentation, and honestly? it's a short one, so we're gonna get through it together. grab a snack. 🍓

✨ NAME ✨

ALTER_OPERATOR_CLASS — change the definition of an operator class. that's it, that's the whole vibe. 💫

---

🦋 SYNOPSIS 🦋

like all good Postgres statements, there are three separate moods you can be in:

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

three little blocks, three little jobs. no cap. 🎀

🌸 DESCRIPTION 🌸

ALTER OPERATOR CLASS changes the definition of an operator class. that's the whole sentence, she's concise, she's an icon. 👑

now — the part where you actually have to be allowed to do this, because Postgres is not about to let just anyone waltz in:

• you must own the operator class to use ALTER OPERATOR CLASS. it's giving main character energy but you gotta be the owner main character.
• to alter the owner, you must be able to SET ROLE to the new owning role. so, like, you have to be able to become them. 🧚
• and that new owning role must have CREATE privilege on the operator class's schema. both boxes checked or we don't go. ✔️

the manual literally explains why these restrictions exist: "(These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator class anyway.)" — so it's basically Postgres making sure you can't cheat your way into powers you couldn't get the honest way. and yes, the superuser loophole is real. superusers do whatever they want, always have, always will. 💀

⭐ PARAMETERS ⭐

okay, the cast of characters, one by one:

• name — the name of an existing operator class. it can be optionally schema-qualified, so you can be as specific as you like. bebou. 🫶
• index_method — the name of the index method this operator class is for. iykyk.
• new_name — the new name of the operator class. fresh start, new you. 💖
• new_owner — the new owner of the operator class. hand over the keys. 🔑
• new_schema — the new schema for the operator class. moving day. 🚚

💀 COMPATIBILITY 💀

there is no ALTER OPERATOR CLASS statement in the SQL standard.

that's right — nothing. nada. zero. this is a Postgres-exclusive situation, we're off the map, there's no standard to be compatible with. lowkey liberating fr fr. 🌈

🔥 SEE ALSO 🔥

go read these next, bestie, they're the whole friend group:

• CREATE OPERATOR CLASS (CREATE_OPERATOR_CLASS(7)) — birth.
• DROP OPERATOR CLASS (DROP_OPERATOR_CLASS(7)) — destruction.
• ALTER OPERATOR FAMILY (ALTER_OPERATOR_FAMILY(7)) — the cousin who also needs altering sometimes.

and that's the page!! short, snappy, slay. ✨
