请注意，ALTER SYSTEM set log_error_verbosity TO DEFAULT 可能不会产生预期的效果

postgres=# SHOW log_error_verbosity ;
 log_error_verbosity
---------------------
 verbose
(1 row)

postgres=# ALTER SYSTEM set log_error_verbosity TO default;
ALTER SYSTEM

postgres=# SELECT pg_reload_conf();
 pg_reload_conf
----------------
 t
(1 row)

postgres=# SHOW log_error_verbosity ;
 log_error_verbosity
---------------------
 verbose
(1 row)

要应用字面值 default，请执行

postgres=# ALTER SYSTEM SET log_error_verbosity TO 'default';
ALTER SYSTEM

postgres=# SELECT pg_reload_conf();
 pg_reload_conf
----------------
 t
(1 row)

postgres=# SHOW log_error_verbosity ;
 log_error_verbosity
---------------------
 default
(1 row)
