01004 — string_data_right_truncation

01004 names right truncation reported as a warning condition. No resolved 18.6 core/contrib report group was found, so this page does not assign a particular cast, encoding path, client, or message.

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

Definition PG 18

01004 — string_data_right_truncation

At a glance {#at-a-glance}

01004 names right truncation reported as a warning condition. No resolved 18.6 core/contrib report group was found, so this page does not assign a particular cast, encoding path, client, or message.

Meaning {#meaning}

The definition names right truncation as a warning condition. Without a resolved call group, the accepted truncation behavior, data preservation, and producer remain unknown.

Messages and diagnostics {#messages}

No resolved 18.6 message variant was found. Preserve the exact value/column context, declared and received lengths when available, encoding, producer version, and complete diagnostics.

Diagnosis {#diagnosis}

Locate the source that emitted the code and compare its length and encoding rules with the value being transferred. Distinguish a warning that preserves a truncated value from an error that rejects the statement; the SQLSTATE alone does not decide that behavior.

Response {#response}

Use the producer's supported length or encoding adjustment and verify whether data was intentionally truncated. Do not silently retry the same input when information may already have been lost.

Versions {#versions}

01004 is present from the locked 9.0.23 snapshot through 18.6 and 19 Beta 3, with known_present_by 7.4. The available evidence establishes catalogue presence, not a current core emission path.

Related {#related}

01003 concerns null elimination; 01008 concerns zero-bit padding; 22001 is a separate error-category string truncation condition.
