01008 — implicit_zero_bit_padding

01008 names a warning-category condition for implicit zero-bit padding. No resolved 18.6 core/contrib report group was found, so no specific bit-string conversion or message is confirmed.

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

Definition PG 18

01008 — implicit_zero_bit_padding

At a glance {#at-a-glance}

01008 names a warning-category condition for implicit zero-bit padding. No resolved 18.6 core/contrib report group was found, so no specific bit-string conversion or message is confirmed.

Meaning {#meaning}

The definition names implicit zero-bit padding as a warning condition. The fixed source scan does not locate the conversion or interface that would produce it.

Messages and diagnostics {#messages}

No resolved 18.6 message variant was found. Preserve the producer, source and destination bit-string types, declared lengths, and complete diagnostic.

Diagnosis {#diagnosis}

Locate the actual type-conversion or driver path and compare its padding rule with the declared bit length. Do not infer padding from an ordinary string truncation or from a query that returns no rows.

Response {#response}

Use the producer's explicit bit length or conversion form when padding is unintended, and verify the resulting value. Do not treat a warning code as proof that a statement was rolled back.

Versions {#versions}

01008 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 definition presence only.

Related {#related}

01004 concerns string truncation; 01003 concerns null elimination; 22021 is an encoding error category.
