Tom,
Let me start this out by voting the things I think we can drop until 8.5:
* gettext plurals patch needs some polishing
-- revert patch, save for 8.5
# adjust information_schema precision and scale fields?
-- save for 8.5
# instrument the Windows shared memory reattachment problem?
-- as much as I'd like to do this, the solution could be as bad as the
problem; we'd need more testing time for new instrumentation. Will have
to deal with via testing patched versions.
# tweak the ordering heuristics for parallel pg_restore?
-- beta2 version is "good enough"; further improvements should be saved
for 8.5.
# change or at least redocument from_collapse_limit?
-- should be doc patch only. Robert Haas should write it.
# revisit increase of default_statistics_target?
-- No. Still appears to be artifact of DBT2. Can't reproduce the issue
using pgbench, or any other test. Still investigating.
Other questions:
# cost_nestloop and cost_hashjoin are broken for SEMI and ANTI joins
* tgl says: I think this is mostly dealt with but it could use
performance testing.
Mark? Jignesh? Can you test this?
