I think Sean's idea is not to make it "just as easy as MySQL", it's to
make it "the *same* as MySQL", for the benefit of those that refuse to
learn differently. Them as won't adjust to "\dt" in place of "show
tables" aren't likely to adjust to "select * from tables" either.
Not even (maybe especially not) if it's arguably a standard.
I think the idea has some merit; although I wonder whether it wouldn't
be smarter to put the code in the backend so that you don't need a
parser in psql. The SHOW code could fall back to looking at these
possibilities after it fails to find a match to a GUC variable name.
