DROP_OPERATOR_CLASS(7pg14)

💅 DROP_OPERATOR_CLASS 💅

okay bestie, so this is the DROP OPERATOR_CLASS page from the PostgreSQL 14.24 docs — yes, that's DROP OPERATOR CLASS, the one that goes poof on an operator class. iykyk 🦋

---

✨ SYNOPSIS ✨

DROP OPERATOR CLASS [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ]

like, that's the whole vibe. read it, memorise it, slay. 👑

---

🌸 DESCRIPTION 🌸

so DROP OPERATOR CLASS drops an existing operator class. that's it, that's the job. 💅

but — and this is the main character rule — to actually run this command you must be the owner of the operator class. no ownership, no dropping. periodt.

also important: DROP OPERATOR CLASS does not drop any of the operators or functions referenced by the class. they stay. they're fine. they're thriving. 🫶

and if there are any indexes depending on the operator class, you'll need to specify CASCADE for the drop to complete. no cascade, no completion. 😭

---

🎀 PARAMETERS 🎀

• IF EXISTS — do not throw an error if the operator class does not exist. a notice is issued in this case. so like, no dramatic meltdown if it's already gone, just a lil heads up. 🙈
• name — the name (optionally schema-qualified) of an existing operator class. yes, schema-qualified is allowed, go off. ✨
• index_method — the name of the index access method the operator class is for. it's giving "which index access method is this for" energy. 💖
• CASCADE — automatically drop objects that depend on the operator class (such as indexes), and in turn all objects that depend on those objects (see Section 5.14). it's a whole chain reaction, lowkey iconic. 🔥
• RESTRICT — refuse to drop the operator class if any objects depend on it. this is the default. the cautious queen we all need. 👑

---

💀 NOTES 💀

DROP OPERATOR CLASS will not drop the operator family containing the class, even if there is nothing else left in the family — in particular, in the case where the family was implicitly created by CREATE OPERATOR CLASS. 😳

an empty operator family is harmless, but for the sake of tidiness you might wish to remove the family with DROP OPERATOR FAMILY; or perhaps better, use DROP OPERATOR FAMILY in the first place. ngl that last tip is the real slay. 🧚

---

🌈 EXAMPLES 🌈

remove the B-tree operator class widget_ops:

DROP OPERATOR CLASS widget_ops USING btree;

⭐ heads up bestie: this command will not succeed if there are any existing indexes that use the operator class. add CASCADE to drop such indexes along with the operator class. 💅

---

🌟 COMPATIBILITY 🌟

there is no DROP OPERATOR CLASS statement in the SQL standard. so cute of the standard, honestly. it's giving "we don't do that here". 💀
