There is always the biggest evil of all... Putting SHOW / DESCRIBE / HELP commands into the backend itself. I'm sure the pgAdmin group likes that idea (they're probably tired of maintaining 4 different versions of queries for getting a list of tables). Any solution to make psql backward or forward compatible should go an additional step to assist other frontends as well.
All that means for phpPgAdmin and pgAdmin is that we'll have to support 5 different queries :P
We could use information_schema...
