config_file_error Config File Error — SQLSTATE F0000

The server reports SQLSTATE F0000 (config_file_error), a condition in the Configuration File Error class.

• The error is written to the server log and returned to the client carrying SQLSTATE F0000.
• Any driver (libpq, JDBC, psycopg, npgsql, pgx) surfaces this code in its error object so you can branch on it programmatically.
• PL/pgSQL can trap it by name: EXCEPTION WHEN config_file_error THEN.

Severity: ERROR  |  PostgreSQL versions: 12, 13, 14, 15, 16, 17

Reproduce with the exact statement and read the full message in the server log (raise log_min_messages / set log_min_error_statement for more context).

F0000 belongs to Class F0 — Configuration File Error. In this class, a configuration file is invalid.

The first two characters (F0) identify the error class, so application code can match the whole class via F0000 when the specific code is not needed.

Fix the syntax in postgresql.conf/pg_hba.conf, then reload (SELECT pg_reload_conf();) or restart; the log names the offending line.
