per-column options for btree indexes. The planner's support for this is still pretty rudimentary; it does not yet know how to plan mergejoins with nondefault ordering options. The documentation is pretty rudimentary, too. I'll work on improving that stuff later. Note incompatible change from prior behavior: ORDER BY ... USING will now be rejected if the operator is not a less-than or greater-than member of some btree opclass. This prevents less-than-sane behavior if an operator that doesn't actually define a proper sort ordering is selected.

when collapsing of JOIN trees is stopped by join_collapse_limit. For instance a list of 11 LEFT JOINs with limit 8 now produces something like ((1 2 3 4 5 6 7 8) 9 10 11 12) instead of (((1 2 3 4 5 6 7 8) (9)) 10 11 12) The latter structure is really only required for a FULL JOIN. Noted while studying an example from Shane Ambler.

hash joins with the estimated-larger relation on the inside. There are several cases where doing that makes perfect sense, and in cases where it doesn't, the regular cost computation really ought to be able to figure that out. Make some marginal tweaks in said computation to try to get results approximating reality a bit better. Per an example from Shane Ambler. Also, fix an oversight in the original patch to add seq_page_cost: the costs of spilling a hash join to disk should be scaled by seq_page_cost.

sets the items, and serializes the value back (rather than adding an arbitrary number of XML preambles as before). The libxml memory management via palloc had to be disabled because it crashes when libxml tries to access memory that was helpfully freed earlier by PostgreSQL. This needs further thought.

database privileges from a pre-8.2 server. This ensures that the reloaded database will maintain the same behavior it had in the previous installation, ie, everybody has connect privilege. Per gripe from L Bayuk.
