SHOW ALL as a query result

Hi All,

Now that Tom's modified the EXPLAIN output to appear as a query result,
maybe SHOW and SHOW ALL should also be modified in that way.  The current
NOTICE: business is a bit messy, and it sure would assist projects just as
pgAccess, phpPgAdmin and pgAdmin with displaying configuration!

Also, what else could be usefully modified?

Chris

ps.
