HV00L — fdw_unable_to_create_execution

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.

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

HV00L — fdw_unable_to_create_execution

At a glance {#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 {#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 {#messages}

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 {#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 {#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 {#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.

Related {#related}

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