a lie on many Unixen), invoke listen() with MIN(MaxBackends*2, 10000).
The clamp value 10000 is configurable in config.h.in, if that proves
to be necessary --- hopefully it won't.
This makes VACUUM work properly with partial indexes, and avoids memory
leakage with functional indexes. Also, suppress complaint about fewer
index tuples than heap tuples when the index is a partial index.
From Martijn van Oosterhout.
USER and ALTER USER to appear in any order, not only the fixed order
they used to be required to appear in.
Also, some changes from Tom Lane to create a FULL option for VACUUM;
it doesn't do anything yet, but I needed to change many of the same
files to make that happen, so now seemed like a good time.

layouts for PyGreSql. Also install into site-packages now, as officially
recommended. And pgdb.py is also installed now, used to be forgotten.

documentation to match code.
* NULLs are sorted differently in 7.2
* table correlation names are supported
* GROUP BY, ORDER BY unrelated is supported since 6.4
* ESCAPE/LIKE only supported since 7.1
* outer joins only since 7.1
* preferred term for procedure is "function"
* preferred term for catalog is "database"
* supports SELECT for UPDATE since 6.5
* supports subqueries
* supports UNION; supports UNION ALL since 7.1
* update some of the max lengths to match reality
* rearrange some functions to match the order in the spec
for easier maintenance
redirections between the build files, which didn't work completely. Now
you just go to the directory of your choice and run make. Clean up the
build files to have a logical order, fix the unnecessary rebuilds, prevent
the deleting targets from removing files they're not responsible for. Ant
1.3 does not have a bug. It deletes directories just fine if you follow
the documentation.
constraint. This case (a) is useless, (b) violates SQL92, and
(c) is certain to cause a failure downstream when we try to create
an index with duplicated column names. So give an appropriate error
message instead of letting the index failure occur. Per report from
Colin Strickland. NOTE: currently, CREATE INDEX fooi ON foo(f1,f1)
still fails with 'cannot insert duplicate key' error. Should we
change that too? What about functional indexes?
object inside the initialization section instead of doing it everytime
the setTimestamp method is called. Thanks to Dave Harkness for this
suggestion.

--verbose messages, which had not been considered so far. Output to the
terminal should okay now; comments written into the dump are still English
only, which may or may not be the desirable thing.
useful as yet, since its primary source of information is (full) VACUUM,
which makes a concerted effort to get rid of free space before telling
the map about it ... next stop is concurrent VACUUM ...
immediately, we will fork a child even if the database state does not
permit connections to be accepted (eg, we are in recovery mode).
The child process will correctly reject the connection and exit as
soon as it's finished collecting the connection request message.
However, this means that reaper() must be prepared to see child
process exit signals even while it's waiting for startup or shutdown
process to finish. As was, a connection request arriving during a
database recovery or shutdown would cause postmaster abort.
