+1. That doesn't force us to implement a whole new set of commands and
syntax to describe stuff in the backend, duplicating the \d commands,
but is polite to the users, and immediately guides them to the right
commands.
You could even do that in the backend for a few simple commands like
SHOW TABLES:
ERROR: syntax error at "SHOW TABLES"
HINT: To list tables in the database, SELECT * FROM pg_tables or use the
\d psql command.
