25008 — held_cursor_requires_same_isolation_level

PostgreSQL SQLSTATE 25008: the held-cursor isolation-level condition and its source-only boundary.

25008 — held_cursor_requires_same_isolation_level

At a glance

25008 is reserved for a held cursor whose transaction isolation level is not compatible with the required operation. The fixed PostgreSQL 18.6 core scan has no direct report group for it.

Meaning

This is narrower than 24000 invalid cursor state and unrelated to the general 40001 serialization retry path. A cursor being held across transactions does not by itself prove that 25008 was emitted.

Diagnosis

Capture the cursor declaration, holdability, isolation level of both transactions, and exact SQLSTATE from the actual reporting implementation. This fixed evidence provides no message template or copyable SQL trigger.

Response

Keep the cursor and consuming transaction at a compatible isolation level, or close and re-declare it according to the API contract. Do not substitute a 24000 repair or a generic rollback without the actual state.

Source message and runtime boundary

The fixed errcodes.txt row defines the condition and macro; the resolved call scan in raw/calls/REL_18_6.jsonl contains no direct report group, so this batch publishes no message template and constructs no natural SQL trigger.

Applicability boundary and case

The selected runner cases on PostgreSQL 18.6 and 10.21 are not_applicable; they record the source boundary and contain no copyable SQL trigger. Structured evidence · case export

Versions and limits

The generated facts record the locked catalogue membership. The selected latest and PG10 cases intentionally remain source-only and not_applicable.

24000 invalid cursor state, 25004 branch transaction isolation, 40001 serialization failure.
