PostgreSQL Error HV005: FDW Column Name Not Found
Description
Error HV005, 'fdw column name not found', indicates an issue where PostgreSQL's Foreign Data Wrapper (FDW) cannot locate a specified column in the remote table it is trying to access. This typically occurs when there's a discrepancy between the column definitions known to the local foreign table and the actual columns present in the remote data source.
Error Message
fdw column name not found
Known Causes
4 known causesRemote Column Mismatch
The column name referenced in your local `CREATE FOREIGN TABLE` definition or query does not exist in the actual remote table schema.
Remote Schema Changes
The remote table schema has changed (e.g., a column was renamed, dropped, or its case changed) since the foreign table definition was created or last synchronized.
Typographical Error
A simple typo exists in the column name specified within your `CREATE FOREIGN TABLE` statement, `IMPORT FOREIGN SCHEMA` command, or a query targeting the foreign table.
Case Sensitivity Issues
The foreign table definition uses a different case for a column name than the actual remote column, and the FDW or remote database enforces case sensitivity.
