# 38004

## At a glance {#at-a-glance}

The Class 38 member is a standard reading-data restriction, but the bounded PostgreSQL 18.6 core/contrib scan found no resolved report group. It should remain separate from 2F004.

## Meaning {#meaning}

Only the enforcing external routine implementation can identify the declaration, read operation, and message fields. The catalogue identity does not prove a backend language rule.

## Messages {#messages}

No fixed PostgreSQL message variant was adopted because the bounded scan did not resolve a native report group.

## Diagnosis {#diagnosis}

Record the routine owner and access declaration, then read its fixed source or protocol mapping. If the server returned 2F004 instead, follow that member and its owner.

## Response {#response}

Adjust the external routine contract or call only as documented. Do not add a blanket retry for a rejected read.

## Versions {#versions}

The locked catalogue places this condition at least by PostgreSQL 7.4. The facts block lists the published snapshots; source-path status is limited to the fixed PostgreSQL 18.6 evidence below.
