I am new to Postgresql. I am using SQL shell (psql) for interacting with the database. When I use psql commands, it is not displaying any output. I am using psql(13.3) version. When I use psql --help, as per documentation, it should display the available options. But I didnt get any output displayed. Similarly when I use another command starting with psql, it is not displaying any results.
谁能帮助我这样做?
