Great TODO updates from Tom:
< Currently SIGTERM of a backend can lead to lock table corruption. > Lock table corruption following SIGTERM of an individual backend > has been reported in 8.0. A possible cause was fixed in 8.1, but > it is unknown whether other problems exist. This item mostly > requires additional testing rather than of writing any new code. < o Allow postgresql.conf values to be set so they can not be changed < by the user 166c167,171 < * %Remove Money type, add money formatting for decimal type > * Improve the MONEY data type > > Change the MONEY data type to use DECIMAL internally, with special > locale-aware output formatting. > 225c230 < o %Allow MIN()/MAX() on arrays > o -Allow MIN()/MAX() on arrays 228c233 < o Modify array literal representation to handle array index lower bound > o -Modify array literal representation to handle array index lower bound 235a241 > o Auto-delete large objects when referencing row is deleted < Currently large objects entries do not have owners.
