Bug fixes:
PreparedStatement.setObject didn't handle short's
ResultSet.getDate() now handles null dates (returns null rather
than a NullPointerException)
ResultSetMetaData.getPrecision() now returns 0 for VARCHAR
New features:
Field now caches the typename->oid in a Hashtable to speed things
up. It removes the need for some unnecessary queries to the
backend.
PreparedStatement.toString() now returns the sql statement that
it will send to the backend. Before it did nothing.
DatabaseMetaData.getTypeInfo() now does something.

This fixes a problem in ResultSet.getDate() when the column is NULL
(reported by Vincent Partington <Vincent.Partington@nmg.nl>)
And fixes a problem with Field's (ResultSet.getObject() was proving to be
slow as it repetedly send queries for oid -> name mapping - fixed by
creating a cache. (reported by Mario Ellebrecht <ellebrec@nads.de>)

Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.
It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.
This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )
This patch is against the 6.3 sources, as it took a while to
complete.
Please review and apply,
Cheers,
Jeroen van Vianen

1) DatabaseMetaData.getPrimaryKeys() would fail saying that there
is no
table t.
2) PreparedStatement.getObject() was missing some break statements,
which
was causing updates not to work with JBuilder (supplied by Aaron
Dunlop).

Ok, this fixes three things:
1. It seems (from tests submitted by two people with JBuilder) that
JBuilder expects a responce from ResultSetMetaData.getPrecision() &
getScale() when used on non numeric types. This patch makes these
methods return 0, instead of throwing an exception.
2. Fixes a small bug where getting the postgresql type name returns null.
3. Fixes a problem with ResultSet.getObject() where getting it's string
value returns null if you case the object as (PGobject), but returns
the value if you case it as it's self.

This patch fixes the following:
* Fixes minor bug found in DatabaseMetaData.getTables() where it doesn't
handle default table types.
* It now reports an error if the client opens a database using
properties, and either the user or password properties are missing. This
should make the recent problem with Servlets easier to find.
* Commented out obsolete property in Driver.getPropertyInfo()

[This is a repost - it supercedes the previous one. It fixes the patch so
it doesn't bread aix port, plus there's a file missing out of the
original post because difforig doesn't pick up new files. It's now
attached. peter]
This patch brings the JDBC driver up to the current protocol spec.
Basically, the backend now tells the driver what authentication scheme to
use.
The patch also fixes a performance problem with large objects. In the
buffer manager, each fastpath call was sending multiple Notifications to
the backend (sometimes more data in the form of notifications were being
sent than blob data!).

This patch fixes a few results in DatabaseMetaData, and updates the README
and TODO files (the later being a new file).
The TODO file lists the things that need to be looked into after 6.2 is
released, and describes the problem with Large Objects.

I've found a problem in the Postgresql jdbc driver.
"ReceiveInteger" shifts a received byte right instead of left.
This means that only the least significant byte is read into the int.
