DROP_FOREIGN_DATA_WRAPPER(7pg15)

💅 NAME 💅

DROP_FOREIGN_DATA_WRAPPER — remove a foreign-data wrapper. That’s the whole assignment, bestie: deleting a foreign-data wrapper that already exists. This is manual page 7pg15 for PostgreSQL 15.19 docs, and we are gonna make it make sense 🫶

---

🌸 SYNOPSIS 🌸

DROP FOREIGN DATA WRAPPER [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

okay so the grammar is literally right there: optional IF EXISTS, one name, maybe more names via , ..., then choose CASCADE or RESTRICT. No cap, that’s the vibe-check version of the synopsis ✨

---

🦋 DESCRIPTION 🦋

DROP FOREIGN DATA WRAPPER removes an existing foreign-data wrapper. To execute this command, the current user must be the owner of the foreign-data wrapper. That’s the permission plot twist: owner only, bestie 👑

---

💖 PARAMETERS 💖

• IF EXISTS — Do not throw an error if the foreign-data wrapper does not exist. A notice is issued in this case. It’s giving gentle skip instead of dramatic explosion 😌
• name — The name of an existing foreign-data wrapper. It has to already be a thing, fr fr.
• CASCADE — Automatically drop objects that depend on the foreign-data wrapper (such as foreign tables and servers), and in turn all objects that depend on those objects (see Section 5.14). This is the full chain-reaction energy 🔥
• RESTRICT — Refuse to drop the foreign-data wrapper if any objects depend on it. This is the default. So if you don’t say anything, PostgreSQL is lowkey protective 🛡️

🎀 EXAMPLES 🎀

Drop the foreign-data wrapper dbi:

DROP FOREIGN DATA WRAPPER dbi;

That’s it. Iconic. One line, no crumbs 💅

---

🌈 COMPATIBILITY 🌈

DROP FOREIGN DATA WRAPPER conforms to ISO/IEC 9075-9 (SQL/MED). The IF EXISTS clause is a PostgreSQL extension. So yes: standards-approved slay, with a little PostgreSQL-specific sparkle ✨

byeee 🫶 this was PostgreSQL 15.19, dated 2026. Stay hydrated, and remember: CASCADE has main character energy for a reason 💀✨
