Is that the same as an 'impossible to do otherwise' case?

Edit: I should say 'currently impossible' since as I noted, I can imagine being able to build SQL queries around PSSM comparisons and the like. I just can't build a system to last 5+ years around something that might be available at some point.

Since I can't reply directly- agreed :)

That comment was based on your "into Postgres wouldn't be impossible" phrase.

No fair enough of its the only way you can get things to work. I still see lots of people jumping on the "big data" bandwagon with very moderate sized data.
