The set of things that is known about an installed extension is quite
a bit different from what is known about an uninstalled-but-available
one. To make \dx print both categories would require dumbing it down
to print only the intersection of those things, or else some fancy
footwork and a lot of NULL column values. -1 for that. (This is exactly
why pg_available_extensions is separate from pg_extension in the first
place.)
I'm okay with inventing some new command like "\dxu" or "\dxa" (mnemonic
"uninstalled" or "available" respectively).
