If you like the psql client then have a look at a graphical "psql" CGI
program!!!
It's just one file twdba.cgi to put in your cgi-bin directory and your
browser does the rest.
http://home.planet.nl/~radejong (TWDBA Download button)
You see the \? tricks only work with that particular psql client and the
engine does not honor them from another client.
You'll love it!!!
