Meaning

An event-trigger helper was called without the state it requires. The fixed messages identify sql_drop, table_rewrite, or a general event-trigger function context, so this is a call-context violation rather than an object-existence error.

Diagnosis

Identify the helper and required event context from the message. Check whether the call belongs in a sql_drop, table_rewrite, or other event-trigger function.

Response

Move the helper into the required event-trigger context or remove the invalid call; replaying the same DDL does not change that context.

Versions

The locked catalogue records this condition from 9.5.0 in the listed formal snapshots and 19beta3; fixed source coverage is PostgreSQL 18.6.
