The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/ddl-rowsecurity.html 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.
