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.

Evidence belongs to the frozen source and runtime versions listed here. It is not a runtime verification of the selected manual version.
HV00M is fdw_unable_to_create_reply in SQL/MED Class HV.
Method: Read the fixed definition row and macro.
No direct HV00M report group was resolved in the locked PostgreSQL 18.6 core/contrib call scan.
Method: Compare resolved report groups with the macro mapping.
Limits: The generic FDW API boundary does not identify an emitter for this SQLSTATE. The scan does not cover external wrappers, drivers, remote systems, or user callbacks.
