the first result in the DB-API compliant wrapper. It turned out that the bug
was way down in the C code.

Allow pg_shadow to be MD5 encrypted.
Add ENCRYPTED/UNENCRYPTED option to CREATE/ALTER user.
Add password_encryption postgresql.conf option.
Update wire protocol version to 2.1.

for speed reasons; its result type also changes to int8.  avg() on these
datatypes now accumulates the running sum in int8 for speed; but we still
deliver the final result as numeric, so that fractional accuracy is
preserved.

count() now counts and returns in int8, not int4.  I am a little nervous
about this possibly breaking users' code, but there didn't seem to be
a strong sentiment for avoiding the problem.  If we get complaints during
beta, we can change count back to int4 and add a "count8" aggregate.
For that matter, users can do it for themselves with a simple CREATE
AGGREGATE command; the int4inc function is still present, so no C hacking
is needed.

Also added max() and min() aggregates for OID that do proper unsigned
comparison, instead of piggybacking on int4 aggregates.

initdb forced.

a tad sloppy about generating the targetlist for some nodes, by generating
a tlist entry that claimed to be a constant when the value wasn't actually
constant.  This caused setrefs.c to do the wrong thing later on.

syntax for language names (instead of 'string').

createlang now handles the case where a second language uses the same call
handler as an already installed language (e.g., plperl/plperlu).

droplang now handles the reverse case, i.e., dropping a language where
the call handler is still used by another language.  Moreover, droplang
can now be used to drop any user-defined language, not just the supplied
ones.

From Joe Conway.

Needed to keep pg_dump from getting confused.

Don't hardcode the maximum accepted server version, use PG_VERSION instead.
Install a notice processor so notices are handled like error messages.
Word smithing.

case where there are resjunk columns in the query.

awhile, but the man page didn't know it.

Other small improvements.

our own code ...

default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.

Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.

initdb forced.

appears to be duplicated (two identical <listitems> right after each
other). Here is a quick patch to remove one instance of it.
