I will work on a list this week.  It will have the same format as usual,
if that is OK.

> Additional items:
> 
> AT TIME ZONE clause for date/time types
> OVERLAPS operator support rewritten
> 
> WAL --- fsync reliability without the performance hit
> TOAST --- 8K row limit is no longer significant
> outer joins (per SQL92 syntax, not Oracle's)
> subselects in FROM clause
> views and subselects now allow union/intersect/except, order by, limit
> views containing grouping, aggregates, DISTINCT work now
> bit-string types work now
> function manager overhaul: fixes portability problems, NULL-argument
> handling
> memory management overhaul: prevent memory leak accumulation during
> queries
> drop table and rename table are now rollback-able (transaction-safe)
> extensive overhaul of configure/build mechanism
> overhaul of parameter-setting mechanisms (postmaster flags,
> postmaster.opts,
>       etc)
> more efficient large-object implementation
> pg_dump can dump large objects now
> pg_dump does the right thing with user-added objects in template1
> support for binding postmaster's IP socket to a virtual host name
> support for placing postmaster's Unix socket file elsewhere than /tmp
> keep reference counts on syscache entries to avoid dropping still-used
> entries
> Protect against changes in LOCALE environment causing corrupted indexes
> better handling of unknown-type literals (default to string type more
> readily)
> inet/cidr datatypes cleaned up
> LIKE/ESCAPE implemented, also ILIKE (case-insensitive LIKE)
> aggregate-function support redesigned: only one transition function now,
>       cleaner handling of NULLs
> STDDEV() and VARIANCE() aggregates added
> SUM() and AVG() on integer datatypes use NUMERIC accumulators
> Child tables are now scanned by default -- ie, if foo has children then
>       SELECT FROM foo means SELECT FROM foo*.  Ditto for UPDATE and DELETE.
>       Use SELECT FROM ONLY foo if you don't want this behavior.
> vacuum analyze does the analyze part without holding exclusive lock
>
