HV007 — fdw_invalid_column_name

HV007 is an FDW-specific invalid-column-name condition. The 18.6 core/contrib scan found no direct report group, so the wrapper that validates the name and its message must be identified from the actual deployment.

English manual coverage begins with PostgreSQL 8.1. Source history and runtime observations have their own recorded version boundaries.

HV007 — fdw_invalid_column_name

At a glance {#at-a-glance}

HV007 is an FDW-specific invalid-column-name condition. The 18.6 core/contrib scan found no direct report group, so the wrapper that validates the name and its message must be identified from the actual deployment.

Meaning {#meaning}

The name reached the FDW API but violates the wrapper's accepted descriptor or remote naming rules. That is different from HV005, where a name is valid in form but cannot be found, and from core 42703 on a local SQL query.

Messages and diagnostics {#messages}

No fixed PostgreSQL core message is confirmed. Preserve the original quoted/unquoted name, case folding, foreign table, callback phase, and wrapper version.

Diagnosis {#diagnosis}

Inspect the wrapper's name parser and remote identifier rules. Compare pg_attribute.attname, generated query identifiers, and any quoted or case-sensitive remote names. Locate the wrapper's pinned source before assigning a repair to PostgreSQL itself.

Response {#response}

Use a name accepted by both the local foreign-table definition and the remote system, or configure the wrapper's explicit name mapping. Rebuild the foreign descriptor after changing metadata; repeating the same statement is not useful.

Versions {#versions}

HV007 is present from 9.1.0 through 18.6 and 19 Beta 3. The available pre-9 source definition scan did not observe this SQLSTATE.

Related {#related}

HV005 is “column name not found”; HV008 is an invalid column number; 42703 is the local undefined-column code.
