Dear All,
Just confused, why :
postgres=# select current_user;
current_user
--------------
postgres
(1 row)
postgres=# select current_user();
2023-03-20 07:00:02.981 UTC [17281] ERROR: syntax error at or near "(" at character 20
2023-03-20 07:00:02.981 UTC [17281] STATEMENT: select current_user();
ERROR: syntax error at or near "("
LINE 1: select current_user();
^
why current_user() is not recognized?
But the similar function current_database and current_database(), both can work.
Regards,
