The fdw_invalid_option_name error appears when a foreign data wrapper, server, or user mapping receives an option key that it does not recognize.
fdw_invalid_option_name occurs when PostgreSQL receives an option name that the target foreign data wrapper does not support. Use \dF+ or pg_foreign_data_wrapper_options to list valid keys, then ALTER the object and supply an allowed option to resolve the error.
fdw_invalid_option_name
PostgreSQL raises SQLSTATE HV00D (fdw_invalid_option_name) when an option key passed to CREATE FOREIGN DATA WRAPPER, CREATE SERVER, or CREATE USER MAPPING is not on the wrapper’s approved list.
The error stops the DDL statement, preventing configuration drift and runtime failures. Fixing it ensures your foreign tables link correctly to remote data sources.
The most common trigger is a misspelled or version-specific option key. Each FDW exposes its own set of allowable parameters, and PostgreSQL validates them at parse time.
The error can also surface when you copy examples written for a different FDW or for a newer wrapper version that supports additional options.
Identify the object that failed, consult pg_foreign_data_wrapper_options or the extension documentation, and replace or remove the bad key. Use ALTER statements so you do not need to drop dependent foreign tables.
After correction, run ANALYZE on the foreign tables to refresh statistics and confirm connectivity.
During migration, an old script adds option use_remote_estimate to postgres_fdw on servers prior to 9.6. Remove the option or upgrade the FDW.
Copy-pasting an example for mysql_fdw but using postgres_fdw causes key mismatch. Replace mysql-specific keys like init_command with valid postgres_fdw parameters.
Always read the wrapper’s official documentation for the PostgreSQL version you are running. APIs evolve, and option names change.
Validate scripts in a staging database first. Galaxy’s editor highlights unknown FDW options, catching typos before they hit production.
SQLSTATE HV00C (fdw_invalid_option_value): fires when the option value is invalid, not the name. Use correct data types.
SQLSTATE HV005 (fdw_option_name_not_found): appears when retrieving an option that was never set. Check pg_options_to_table results.
Run \dF+ in psql or query pg_foreign_data_wrapper to list the fdwoptions column, then consult the wrapper’s documentation.
No. PostgreSQL validates all option names at statement time. Remove or rename it to proceed.
Only if the new version adds support for the option. Always check release notes and extension versions.
Galaxy’s context-aware linting flags unknown FDW options as you type and offers auto-completion with valid keys, preventing the error before execution.
