The fdw_table_not_found error appears when a query references a foreign table that the foreign data wrapper cannot locate on the remote server.
PostgreSQL fdw_table_not_found occurs when a foreign table named in your query is missing on the remote server or in its schema search path. Verify the remote table name and schema, refresh your foreign table definitions, then rerun the query to resolve the issue.
PostgreSQL Error HV00R: fdw_table_not_found
The fdw_table_not_found error (SQLSTATE HV00R) is raised by PostgreSQL when a Foreign Data Wrapper (FDW) attempts to execute a query against a remote table that it cannot locate.
The planner builds the query locally, but when the FDW contacts the foreign server the server returns an object-not-found response. PostgreSQL converts that response into the fdw_table_not_found condition.
Missing remote table names trigger the error most often.
If the foreign server dropped or renamed a table after the foreign table was created, the FDW record becomes stale.
Mismatched schema search paths also cause failures.
If the FDW connection defaults to a schema that no longer contains the table, the lookup fails even though the table exists elsewhere.
Incorrect case folding and quoting in the foreign table definition can hide the correct object from the FDW.
Confirm the table exists on the foreign server with an independent connection.
If the table was renamed, recreate it or update your foreign table definition.
Run REFRESH FOREIGN TABLE or DROP and CREATE FOREIGN TABLE to align the local definition with the remote schema.
Adjust the fdwoptions such as schema, query, or table_name so that the FDW references the correct object.
Scenario: A staging database is recreated nightly, dropping legacy tables.
Solution: Add a migration step that recreates foreign tables or switch to views that persist across loads.
Scenario: Development servers use mixed-case identifiers. Solution: Quote identifiers consistently in CREATE FOREIGN TABLE statements.
Automate REFRESH FOREIGN TABLE after any upstream schema change.
This keeps local metadata current.
Use explicit schema-qualified names in foreign table definitions to remove reliance on remote search_path settings.
Monitor foreign server logs for object-not-found messages and alert on failures before they affect production queries.
HV00N fdw_unable_to_create_execution: occurs when the FDW cannot build a remote query plan - check permissions.
42703 undefined_column: raised when a referenced column is missing on the foreign server - refresh table definitions.
.
No. REFRESH FOREIGN TABLE only fetches column metadata and does not lock or alter data on the remote server.
Queries hitting the missing foreign table will fail until the definition is corrected. Local tables remain unaffected.
Only if the table truly exists in another schema. If the table was dropped, you must recreate it or point to a new table.
Galaxy shows foreign table metadata inline and alerts on stale definitions. Its AI copilot suggests running REFRESH FOREIGN TABLE after remote schema changes.
