HV00L — fdw_unable_to_create_execution

PostgreSQL SQLSTATE HV00L identifies an FDW failure to create an execution object. Inspect the wrapper’s remote execution setup and resource contract.

HV00L — fdw_unable_to_create_execution

At a glance

HV00L denotes an FDW implementation’s inability to create a remote execution object. No direct 18.6 core/contrib report group was resolved, so the object, remote API, and message are wrapper-specific.

Meaning

The condition name describes failure while a wrapper is creating an execution object before using it for the requested operation. It might involve a remote statement, cursor, plan, or driver object; only the wrapper source can identify which object and stage apply.

Messages and diagnostics

No fixed core message is confirmed. Record the wrapper, remote operation, connection state, option set, and the underlying driver/remote diagnostic if one exists.

Diagnosis

Read the wrapper’s execution creation function and classify the failure as local allocation, remote rejection, invalid options, or connection state. Check server/wrapper/driver versions and whether a prior request left the connection in an unusable state.

Response

Correct the identified option or connection state and recreate the execution object through the wrapper API. For a write, confirm that no remote execution began before repeating it; the condition alone does not establish that boundary.

Versions

The directory contains HV00L from 9.1.0 through 18.6 and 19 Beta 3. The available pre-9 definitions do not show it.

HV00M concerns reply-object creation; HV00N concerns connection establishment; HV001 covers a specific option-allocation path.
