system. Some systems did not understand the 'l' section, and in general
it wasn't entirely appropriate.
On SCO OpenServer, the man pages won't be installed at all until someone
figures out their man system.
Client headers are no longer in a subdirectory, since they have been made
namespace-clean.
Internal libpq headers are in a private subdirectory.
Server headers are in a private subdirectory. pg_config has a new option
to point there.
Since we're assuming a C++ compiler knows what 'bool' is, seems we
should assume it knows 'true' and 'false' too. This prevents problems
on some systems, per report from Leandro Fanzone.
for some reason displays a zero oid differently. Possibly we should
revert that schema change, but it's easy to make pg_dump accept both
spellings so I'll do that for now.
in interfaces/perl5 a brief while ago.
Also, since building PL/Perl without a shared libperl actually works on
some platforms we can enable it there to get some development happening.
I've only checked off linux right now, but others should be added in the
future.
the Admin Guide about routine maintenance tasks. Currently this only
discusses the various reasons for doing VACUUM, but perhaps it could be
fleshed out with topics like log rotation.
longer compiles, due to objects being referenced in this patch that do
not exist in JDK1.1.

The JDBC driver requires
permission java.net.SocketPermission "host:port", "connect";
in the policy file of the application using the JDBC driver
in the postgresql.jar file. Since the Socket() call in the
driver is not protected by AccessController.doPrivileged() this
permission must also be granted to the entire application.

org.postgresql.util.Serialize and org.postgresql.jdbc2.PreparedStatement
that fixes the ability to "serialize" a simple java class into a
postgres table.
The current cvs seems completely broken in this support, so the patch
puts it into working condition, granted that there are many limitations
with serializing java classes into Postgres.
The code to do serialize appears to have been in the driver since
Postgres 6.4, according to some comments in the source. My code is not
adding any totally new ability to the driver, rather just fixing what
is there so that it actually is usable. I do not think that it should
affect any existing functions of the driver that people regularly
depend on.
The code is activated if you use jdbc2.PreparedStatement and try to
setObject some java class type that is unrecognized, like not String or
not some other primitive type. This will cause a sequence of function
calls that results in an instance of Serialize being instantiated for
the class type passed. The Serialize constructor will query pg_class
to see if it can find an existing table that matches the name of the
java class. If found, it will continue and try to use the table to
store the object, otherwise an SQL exception is thrown and no harm is
done. Serialize.create() has to be used to setup the table for a java
class before anything can really happen with this code other than an
SQLException (unless by some freak chance a table exists that it thinks
it can use).
I saw a difference in Serialize.java between 7.1.3 and 7.2devel that I
didn't notice before, so I had to redo my changes from the 7.2devel
version (why I had to resend this patch now). I was missing the
fixString stuff, which is nice and is imporant to ensure the inserts
will not fail due to embedded single quote or unescaped backslashes. I
changed that fixString function in Serialize just a little since there
is no need to muddle with escaping newlines: only escaping single quote
and literal backslashes is needed. Postgres appears to insert newlines
within strings without trouble.
buffer manager with 'pg_clog', a specialized access method modeled
on pg_xlog. This simplifies startup (don't need to play games to
open pg_log; among other things, OverrideTransactionSystem goes away),
should improve performance a little, and opens the door to recycling
commit log space by removing no-longer-needed segments of the commit
log. Actual recycling is not there yet, but I felt I should commit
this part separately since it'd still be useful if we chose not to
do transaction ID wraparound.
