I'm not convinced that we should start adding syntax helpers like that to psql. For now it is an arbitrary subset of MySQL stuff, are we going to add oracle/db2/mssql/drizzle/mariadb and whatnot later on? Also I can already see people asking "well you already know that this is that command - why not emulate it fully?".

Good points. However, it only takes effect in interactive mode, so I
don't see it as a promise to do much. I'll make an analogy to:

  $ git difff
  git: 'difff' is not a git-command. See 'git --help'.

  Did you mean this?
          diff

well the actual output is just:

:~$ git difff
git: 'difff' is not a git-command. See 'git --help'.


which is more or less the same as:

postgres=# \mysql
Invalid command \mysql. Try \? for help.

so I don't really see why we need to add some random second guessing of what the user actually wanted (and if he is indeed a mysql refugee he can always use "help" and go on from there).
