The fdw_option_name_not_found error appears when an OPTION key used in CREATE or ALTER FOREIGN DATA WRAPPER, SERVER, or USER MAPPING does not match any supported option for that object.
fdw_option_name_not_found (SQLSTATE HV00J) means PostgreSQL cannot recognize the option name supplied to a FOREIGN DATA WRAPPER statement. Verify the spelling, check the foreign extension documentation, and only use options supported by that wrapper to resolve the error.
PostgreSQL Error HV00J
PostgreSQL raises fdw_option_name_not_found (SQLSTATE HV00J) when an OPTION clause lists a key that the targeted foreign data wrapper does not understand. The parser stops before the statement is executed.
The error blocks CREATE or ALTER commands for FOREIGN DATA WRAPPER, SERVER, or USER MAPPING objects.
Fixing it is essential because the object will not be created or updated, preventing access to external data sources.
Misspelled option names trigger the error immediately. PostgreSQL validates each option key against the catalog of valid options for the specific FDW.
Using an option that belongs to another FDW also fails.
Each wrapper maintains its own allowed keys.
Omitting the required extension with CREATE EXTENSION causes the option list to be empty, leading to unrecognized keys.
First, confirm the correct option list in the wrapper documentation or by querying pg_options_to_table().
Second, install or update the extension providing the FDW if it is missing, then retry the command.
Third, rewrite the statement with only valid option keys and values.
While configuring postgres_fdw, typing hostaddr instead of host raises the error.
Replace the key and re-run CREATE SERVER.
Upgrading to postgres_fdw 1.1 removes reconnect_mode; attempting to set it yields the error. Drop the deprecated option in ALTER SERVER.
On AWS RDS, mysql_fdw may lack ssl_mode support. Upgrading the extension to a version that supports ssl_mode resolves the problem.
Always read the FDW docs before adding OPTIONS.
Validate keys using pg_options_to_table() to ensure they exist.
Store working CREATE scripts in Galaxy Collections so teammates reuse vetted statements instead of editing options in Slack snippets.
Automate schema migrations in CI. Run statements in Galaxy’s editor with syntax validation to catch typos early.
fdw_unable_to_create_reply means the FDW could not connect to the remote server.
Check network settings.
fdw_invalid_option_name appears when the option name is spelled correctly but used in a clause that does not support it.
sqlstate 42702 (ambiguous_column) differs because it refers to duplicate column names in SELECT lists, not FDW options.
.
Consult the extension docs or run \h in psql for CREATE SERVER examples. Some FDWs expose pg_options_to_table() for discovery.
No. Use ALTER SERVER or ALTER USER MAPPING with OPTIONS ADD or SET to modify individual keys safely.
No. The parser validates options only during CREATE or ALTER statements. Once the server exists, SELECT works as long as options remain valid.
Galaxy lets you store and endorse correct CREATE statements in shared Collections, reducing manual edits and preventing typos that lead to fdw_option_name_not_found.
