42P12 — Invalid database definition

At a glance

42P12 (invalid_database_definition) This condition names an invalid database definition, but its core emitter was not resolved in this scan.

Meaning

The catalogue condition is defined as invalid_database_definition. The bounded 18.6 call scan did not resolve a core emitting group for this code, so this page gives the condition boundary without inventing a database-operation trigger.

Diagnosis

When it appears, retain the server message, database name, statement, and server log context. First determine whether the response came from PostgreSQL core, an extension, a client-side mapping, or a wrapper; the condition name alone does not identify the failing catalogue object.

Response

Use the resolved message and fixed-version source path to choose a repair. Check the affected database definition and dependencies only after the actual emitter is identified; this bounded scan does not support a more specific SQL recipe or a fixed severity. If the actual response is an ERROR inside an explicit transaction, apply the normal ROLLBACK or pre-error savepoint rule, but do not present that generic protocol recovery as a confirmed 42P12 emitter path.

Messages

No message variant is included because the bounded source scan did not resolve a core emitting group for this condition.

Versions

The locked catalogue shows this condition by PostgreSQL 7.4; behavior here is fixed to PostgreSQL 18.6 source. Catalogue presence is a range boundary, not proof that every message or feature began in that release.
