<h1>HV00M — fdw_unable_to_create_reply</h1>

At a glance

HV00M denotes failure to create an FDW reply object or result channel. The PostgreSQL 18.6 core/contrib scan has no direct resolved report group; the exact object and driver boundary must be read from the installed wrapper.

Meaning

An FDW may create an execution and a separate reply/result object. HV00M names failure of the latter setup; it does not prove that the remote statement was never sent.

Messages and diagnostics

No fixed core message is confirmed. Keep the operation, reply format, connection/handle state, wrapper and driver versions, and any remote diagnostic.

Diagnosis

Trace reply allocation/registration and the point at which the execution object was created. Distinguish local result-buffer failure from a remote protocol rejection. Check whether cleanup left a stale reply handle.

Response

Repair the wrapper's result-channel setup and clean up the affected handle according to its API. Before repeating a write, establish remote completion from the wrapper or remote logs; HV00M does not make an automatic retry safe.

Versions

HV00M is present from 9.1.0 through 18.6 and in 19 Beta 3; no pre-9 definition observation is available.
