Re: About the function current_user

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.
