Re: Why not install pgstattuple by default?

My example is of doing "self-discovery" to see if all needful database
components seem to be properly installed.

E.g. - the app needs pgcrypto, intarray, and a custom data type.  The
install script can consequently inform the production folk either "looks
good", or, alternately, "seems problematic!"

Actually, I haven't coded a sample of the "look for custom SPI & types"
part, but it's a natural extension of what I have.

Of course, it only provides a legitimate test when run on the database
server, which isn't always how production folk want to do it, but that's
part of a different argument...
