TAP, ADQL and PgSphere

[Tom McGlynn]

One possibility is making this a topic for a discussion in the
DAL/Apps session on TAP that is currently scheduled for Wednesday.
It certainly fits into the theme of that session.  If the goal is seen 
as just understanding how someone might use PgSphere in implementing 
ADQL, then I think that's appropriate.

However I could see this going a bit further than that.  E.g., should we 
think about building a Postgres/PgSphere based reference implementation 
of ADQL?  From my reading of the documents that's perfectly feasible but 
would warrant its own session.
