HV014 — fdw_too_many_handles

HV014 identifies an FDW condition involving too many handles. No resolved HV014 report group was found in the locked PostgreSQL 18.6 core/contrib call scan, so no native handle limit or message is attributed.

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

HV014 — fdw_too_many_handles

At a glance {#at-a-glance}

HV014 identifies an FDW condition involving too many handles. No resolved HV014 report group was found in the locked PostgreSQL 18.6 core/contrib call scan, so no native handle limit or message is attributed.

Meaning {#meaning}

A handle can be an implementation-owned reference to a connection, cursor, result, or execution object. The class definition does not specify the handle kind, scope of the limit, or whether the limit belongs to a wrapper, driver, or remote service.

Messages and diagnostics {#messages}

No resolved 18.6 core/contrib message variant was found. Preserve the complete diagnostic, handle kind, count or limit if reported, operation phase, wrapper/driver version, and foreign server identity.

Diagnosis {#diagnosis}

Find the wrapper code that allocates or tracks handles and determine whether the limit is per statement, session, process, server, or remote connection. Check for handles that were not closed after errors, while keeping the wrapper's own ownership rules as the authority.

Response {#response}

Close or release the handles that the wrapper identifies as no longer needed, or use its supported pooling/limit configuration after confirming the scope. If a failed operation may have sent work remotely, verify remote state before retrying it.

Versions {#versions}

HV014 is present in the locked definition snapshots from 9.1.24 through 18.6 and 19 Beta 3, with known_present_by 9.1.0. The available pre-9 definition material does not establish an exact introduction release.

Related {#related}

HV00B is an invalid handle condition; HV00K concerns a reply handle; HV00L concerns creating an execution object.
