22000 — data_exception

22000 is dataexception. The fixed arrayappend path accepts an empty or one-dimensional array argument and reports the dimensionality requirement otherwise; other Data Exception paths belong to their own subsystem.

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

22000

At a glance {#at-a-glance}

22000 is data_exception. The fixed array_append path accepts an empty or one-dimensional array argument and reports the dimensionality requirement otherwise; other Data Exception paths belong to their own subsystem.

Meaning {#meaning}

Messages {#messages}

The confirmed guard raises ERROR with primary message argument must be empty or one-dimensional array. This fixed path has no separate DETAIL or HINT. The page is source-only; no natural runtime observation is claimed.

Diagnosis {#diagnosis}

Check the complete message, the array_append call, and the argument type before changing data. The confirmed path rejects an array argument that is neither empty nor one-dimensional.

Response {#response}

Correct the array shape or use a function contract that accepts the intended dimensions. This is an ERROR: in an explicit transaction, roll back the whole transaction or roll back to a savepoint established before the call before continuing. Re-run only after validating the argument; do not treat every Data Exception as the same repair. No runtime case was run for this page.

Versions {#versions}

The locked catalogue records this condition from 7.4 in the listed formal snapshots and 19beta3; fixed source coverage is PostgreSQL 18.6.
