I agree. I don't see providing the plugin capability should prevent
provision of further features in this area. Indeed, I see it as a way of
encouraging people to write stuff for Postgres, which we then reel
slowly back into core, if it is robust enough and general purpose
enough. My model is PL/Proxy: the capability we will eventually gain in
Core will be because we gave solution designers a free hand to invent
and a free hand to overcome obstacles in months, not years. Solutions
now, better solutions later.

Thank you.
