- Properly drop tables in jdbc regression tests with cascade for 7.3
- problem with Statement.execute() and executeUpdate() not clearing binds
- problem with ResultSet not correctly handling default encoding
- changes to correctly support show transaction isolation level in 7.3
- changed DatabaseMetaDataTest to handle differences in FK names in 7.3
- better fix for dynamically checking server NAME data length
(With the fixes above the jdbc regression tests pass on jdbc2 and jdbc3
against both a 7.2 and 7.3 server)
Patchs submitted by David Wall (d.wall@computer.org):
- problem with getBlob when largeobject oid is null
- improvements to BlobOutputStream
Patch submitted by Haris Peco (snpe@snpe.co.yu):
- problem with callable statement not supporting prepared statement methods

Fixed support in the driver for notifications (added PGConnection.getNotifications()) - problem reported by Benjamin.Feinstein@guardent.com
Worked around server problems with int8/int2 and constants; quote values when they are intended to bind to an int8/int2 column - reported by many
Fixed bug in the Array interface with string parsing not handling escaped characters correctly - reported by devajx@yahoo.com
Added workaround to support 'infinity' and '-infinity' for dates - reported bydmitry@openratings.com
Fixed some performance issues with setBlob - reported by d.wall@computer.org
Added support for using new prepared statements functionality in 7.3 (added PGStatement.setUseServerPrepare() and isUseServerPrepare() methods)

the server. Previously we allocated a new String object for the entire final
query we were sending to the database. If you had a big query, or especially
if you had large bind values you ended up with essentially two copies in memory.
This change will reuse the existing objects and therefore should take 1/2 the
memory it does today for a given query. This restructuring will also allow
in the future the ability to stream bytea data to the server instead of the current approach of pulling it all into memory.
I also fixed a test that was failing on a 7.2 database.
Also renamed some internal variables and some minor cleanup.

of duplicated code between the jdbc1 and jdbc2. This checkin restructures
the code so that the duplication is removed so that the jdbc3 support
can be added without adding yet another copy of everything. Also many
classes were renamed to avoid confusion with multiple different objects
having the same name. The timestamp tests were also updated to add support
for testing timestamp without time zone in addition to timestamp with time zone
