If Tom Lane's working on an interim solution for outer joins, so they don't have to wait for the 7.2 query tree redesign, that's great. I've looked into it myself, and getting the optmizer educated about them is the only really difficult part, at least for the Oracle-like syntax. Tom's the only person who really seems to understand the optimizer, so he's the right person to look into them.
That new PG graphic's cute, I like it.
