The reason for doing it this way is that changing the underlying architecture is really hard, without having to bear an endless hackers bike shed discussion about the best userland syntax to use. It seems a much better approach to do the actually difficult part first, then let the rest to be argued to death by others and let those others do the easy part (and take all the credit along with that); that way, that discussion does not kill other possible uses that the new architecture allows. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
