* Use a binary heap for Merge-Append operations (Abhijit Menon-Sen)
Implement a generic binary heap and use it for Merge-Append operations
which previously used a ad-hoc version.
* Dramatically reduce System V shared memory usage (Robert Haas)
s/eleminates/reduces/ in "This eliminates the requirement of increasing
System V shared memory kernel parameters.". There are still quite some
usecases where some of those need to be touched.
* Improve performance of streaming replication log shipping
... with synchronous_commit = off
* Store WAL in a continuous stream, rather than skipping the last 16MB
segment every 4GB (Heikki Linnakangas)
Should be marked as a potential backward compatibility break, some tools
might need to adapt their logic.
* Add IF NOT EXISTS clause to CREATE SCHEMA (FabrÃzio de Royes Mello)
another broken name :(
* Add pg_dump --jobs to dump in parallel (Joachim Wieland)
Should we mention that this is only working for directory mode dumps?
Some users might be a bit confused otherwise.
* Add infrastructure to better support plug-in background worker processes
(Álvaro Herrera)
... configurable via shared_preload_libraries
* Split out WAL reading as an independent facility
Should mention Heikki as primary author instead of me.
