ALTER_OPERATOR_CLASS(7pg18)

💅 ALTER OPERATOR CLASS 💅

okay bestie, so this is the ALTER OPERATOR CLASS page from the PostgreSQL 18.6 Documentation — yes, manual page 7, we're in the deep lore now. sit down, grab a strawberry, let's talk about changing up your operator class's whole definition. 🍓

---

✨ NAME ✨

ALTER OPERATOR CLASS — change the definition of an operator class. that's it, that's the whole job, and she does it flawlessly. 💅

---

✨ SYNOPSIS ✨

three whole moods, three whole syntaxes. 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 ✨

so ALTER OPERATOR CLASS changes the definition of an operator class. that's the vibe. that's what she's giving. 💖

okay but here's the part where you have to actually be her, because the rules said so:

you must own the operator class to use ALTER OPERATOR CLASS.

and if you're trying to change the owner? bestie, you have to be able to SET ROLE to the new owning role, and that role must have CREATE privilege on the operator class's schema. both. no skipping steps. 🫶

like, why so strict? because these restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the operator class. it's a "no sneaky shortcuts" situation. fair honestly.

BUT — and this is the plot twist — a superuser can alter ownership of any operator class anyway. main character energy only. 👑

---

✨ PARAMETERS ✨

okay here's the cast list, every single one of them, no one gets cut:

• name — the name (optionally schema-qualified) of an existing operator class. yes, an existing one. she has to already be here. 🌸
• index_method — the name of the index method this operator class is for.
• new_name — the new name of the operator class. glow-up name change, go off. ✨
• new_owner — the new owner of the operator class. handing over the keys. 🔑
• new_schema — the new schema for the operator class. moving house, no big deal. 🦋

---

✨ COMPATIBILITY ✨

ngl there is no ALTER OPERATOR CLASS statement in the SQL standard. she's built different, she's original, the standard could never. 💀

---

✨ SEE ALSO ✨

go read these next, i'm obsessed with all of them:

• CREATE OPERATOR CLASS (CREATE_OPERATOR_CLASS(7))
• DROP OPERATOR CLASS (DROP_OPERATOR_CLASS(7))
• ALTER OPERATOR FAMILY (ALTER_OPERATOR_FAMILY(7))

---

and that's the whole page, bestie. 💜
