has an alias SERIAL4 and a sister SERIAL8. SERIAL8 is just the same
except the created column is type int8 not int4.
initdb forced. Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences. (Which is
not out of the question, but I don't wanna do it.)
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.
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.
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.
* Merges identical code from org.postgresql.jdbc[1|2].Statement into
org.postgresql.Statement.
* Moves escapeSQL() method from Connection to Statement (the only place
it's used)
* Minor cleanup of the new isolation level stuff.
* Minor cleanup of version string handling.

2. support for 'pass-by-value' arguments - to test this
we used special opclass for int4 with values in range [0-2^15]
More testing will be done after resolving problem with
index_formtuple and implementation of B-tree using GiST
3. small patch to contrib modules (seg,cube,rtree_gist,intarray) -
mark functions as 'isstrict' where needed.

Here is a context diff from latest cvs
And I see why you couldn't apply the last diff, the setCatalog diff has
been backed out, that was causing the compile problem in the first
place.
This following one needs to be applied to allow the current cvs to

clauses are equal(), before trying to match them up using btree opclass
inference rules. This allows it to recognize many simple cases involving
non-btree operations, for example 'x IS NULL'. Clean up code a little.
Make sure it exits immediately when collector process dies --- in old code,
buffer process would hang around and compete with the new buffer process
for packets. Make sure it doesn't block on writing the pipe when the
collector falls more than a pipeload behind. Avoid leaking pgstats FDs
into every backend.

The Debian bug report says, "The upstream source makes use of NOFILE
unconditionalized. As the Hurd doesn't have an arbitrary limit on the
number of open files, this is not defined. But _SC_OPEN_MAX works fine
and returns 1024 (applications can increase this as they want), so I
suggest the below diff. Please forward this upstream, too."

1) improves performance of commit/rollback by reducing number of round
trips to the server
2) uses 7.1 functionality for setting the transaction isolation level
3) backs out a patch from 11 days ago because that code failed to
compile under jdk1.1
Details:
1) The old code was doing the following for each commit:
commit
begin
set transaction isolation level xxx
thus a call to commit was performing three round trips to the database.
The new code does this in one round trip as:
commit; begin; set transaction isolation level xxx
In a simple test program that performs 1000 transactions (where each
transaction does one simple select inside that transaction) has the
following before and after timings:
Client and Server on same machine
old new
--- ---
1.877sec 1.405sec 25.1% improvement
Client and Server on different machines
old new
--- ---
4.184sec 2.927sec 34.3% improvement
(all timings are an average of four different runs)
2) The driver was using 'set transaction isolation level xxx' at the
begining of each transaction, instead of using the new 7.1 syntax of
'set session characteristics as transaction isolation level xxx' which
only needs to be done once instead of for each transaction. This is
done conditionally (i.e. if server is 7.0 or older do the old behaviour,
else do the new behaviour) to not break backward compatibility. This
also required the movement of some code to check/test database version
numbers from the DatabaseMetaData object to the Connection object.
3) Finally while testing, I discovered that the code that was checked in
11 days ago actually didn't compile. The code in the patch for
Connection.setCatalog() used Properties.setProperty() which only exists
in JDK1.2 or higher. Thus compiling the JDBC1 driver failed as this
method doesn't exist. Thus I backed out that patch.

platforms system(2) gets confused unless the signal handler is set to
SIG_DFL, not SIG_IGN. pgstats.c now uses pqsignal() as it should,
not signal(). Also, arrange for the stats collector process to show
a reasonable ID in 'ps', rather than looking like a postmaster.
Dump the alignment and storage information for user-defined types (how'd
that manage to slip through the cracks?), and don't dump 'shell' types
that don't have typisdefined set. Fix badly broken logic for dependencies
of type definitions (did not work for more than one user-defined type...).
Avoid memory leakage within pg_dump by being more careful to release
storage used by PQExpBuffer objects.
exec_eval_simple_expr shortcut, which was diked out in 7.1 because it
leaked too much space. CVS tip now leaks no memory in Chris Ruprecht's
example, which formerly leaked to the tune of 500 MB. (Much of this
is work that Jan already did; this commit just cleans up around the
edges.)
Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it.
its a function with no expected arguments, so you can use it like:
spi_exec "INSERT INTO mytable(columns...) VALUES(values..)"
set oid [spi_lastoid]
spi_exec "SELECT mytable_id from mytable WHERE oid=$oid"
It just didn't make sense for me to use plpgsql and pltcl, or just screw
them both and use SPI from C.

that call is not needed to prepare for SO_PEERCRED. Also, simplify code
so that #ifdef SO_PEERCRED appears in only one place, to make it easier
to support other platforms with variants of this capability.
points out how silly it is to use Autoconf to test for a preprocessor
symbol, when one can equally easily #ifdef on the symbol itself.
Accordingly, revert configure to prior state and do it that way.

TIOCGWINSZ is defined as follows:

FreeBSD sys/ttycom.h. This file is included by sys/ioctl.h.

This patch tells print.c to know TIOCGWINSZ on Solaris platform. Same code is

number in the data structure so that we can give at least a minimally
useful idea of where the mistake is when we issue syntax error messages.
Move the ClientAuthentication() call to where it should have been in
the first place, so that postmaster memory releasing can happen in a
reasonable place also. Update obsolete comments, correct one real bug
(auth_argument was not picked up correctly).
more care with resjunk tlist entries than it was doing. The original
coding ignored resjunk entries entirely, but a resjunk entry that is
in either the distinctClause or sortClause lists indicates that DISTINCT
ON was used. It's important for ruleutils.c to get this right, else we
may dump views using DISTINCT ON incorrectly.

improve the DISTINCT-ON-clause recognizer routine to not be fooled by out-

This makes the script more legible (IMHO anyway) by reducing the need
to escape quotes, and allows us to execute successive SQL commands in
a single standalone-backend run, rather than needing to start a new
standalone backend for each command. With all the CREATE VIEWs that
are getting done now, this makes for a rather substantial reduction
in the runtime of initdb. (Some of us do initdb often enough to care
how long it runs ;-).)
connection implementations (org.postgresql.jdbc[1|2].Connection) into
their superclass (org.postgresql.Connection).
It also changes the close() methods of Connection and PG_Stream, so that
PG_Stream no longer is responsible for sending the termination packet 'X'
to the backend. I figured that protocol-level stuff like that belonged in
Connection more than in PG_Stream.

in Connection - note: I've updated setCatalog(String catalog) from my previous
diff so it checks whether it is already connected to the specified catalog.

Here's a patch against the current CVS. The changes from the previous

functions do not set errno, so some normal conditions are treated as
fatal errors. e.g. fetching large tuples fails, as at some point recv()
returns EWOULDBLOCK. here's a patch, which replaces errno with
WSAGetLastError(). i've tried to to affect non-win32 code.
