The following documentation comment has been logged on the website:

Description:
On this page I see the following example:
----cut----
=> SELECT current_user;
current_user
--------------
admin
(1 row)
=> select inet_client_addr();
inet_client_addr
------------------
127.0.0.1
(1 row)
=> SELECT current_user;
current_user
--------------
admin
(1 row)
----cut----
One of executions of "SELECT current_user;" is redundant and can be removed.
