psql's backslash commands don't do anything you couldn't do for
yourself.  To see what they're doing, start psql with -E switch to
make it echo the SQL commands it's sending.

One thing you do have to watch out for is that details of the system
catalogs tend to change from release to release, so if you do anything
too fancy you might find it broken at some point in the future...
