ERROR: cannot drop table x because other objects depend on it

Views, foreign keys or other objects depend on what you’re dropping.

Seen on: PostgreSQL

Meaning

The DETAIL/HINT lists dependents. DROP … CASCADE removes them too — review the list first.

Common causes

  • Views built on the table
  • Foreign keys from other tables
  • Functions/triggers referencing it

⚡ Quick fix

  1. Read the dependent objects in DETAIL
  2. Drop or alter dependents first
  3. Use CASCADE only when you intend to drop them

Detailed fix by platform

PostgreSQL

  1. DROP TABLE legacy_orders CASCADE; -- drops dependent views/FKs too

How to diagnose

  1. Dependents — Listed in DETAIL?
  2. Recent change — Did it start after a deploy, upgrade, or configuration change? Compare with the last working version.
