Why it happens

1A required FDW option (e.g., host, dbname, table_name) is missing from the foreign server or foreign table definition

How to reproduce

Missing required FDW option.

trigger — this will ERROR

CREATE SERVER remote_pg FOREIGN DATA WRAPPER postgres_fdw;
-- missing host and dbname options

ERROR: required option "host" is missing

Fix 1: Provide all required options in the FDW object definition

When creating a foreign server or foreign table.

fix

CREATE SERVER remote_pg
  FOREIGN DATA WRAPPER postgres_fdw
  OPTIONS (host 'remote.host', dbname 'remotedb', port '5432');

Why this works

Consult the FDW documentation for the required options and include them all in the CREATE SERVER or CREATE FOREIGN TABLE statement.
