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.
Sources
Source messages, line anchors, and evidence limits are recorded in authored evidence.
- The fixed definition is recorded in
errcodes.txt.
Source evidence
Evidence belongs to the frozen source and runtime versions listed here. It is not a runtime verification of the selected manual version.
42P12 is the invalid_database_definition condition in Class 42.
Method: Read fixed REL_18_6 errcodes.txt and locked facts.
Limits: Identity does not enumerate all source branches or client failures.
The bounded REL_18_6 call scan did not resolve a core emitting group for this condition.
Method: Read all candidate records for this code in raw/calls/REL_18_6.jsonl.
Limits: This is a scan boundary, not proof that the condition is never emitted.
Locked catalogue snapshots show this condition by PostgreSQL 7.4; source behavior here is fixed at PostgreSQL 18.6.
Method: Read locked catalogue facts and definition snapshot.
Limits: First observed release is a lower bound, not precise behavioral introduction.
