In looking at the 7.1beta1 code for JDBC, I noticed that support was
added to support character set encodings.  However I noticed that the
encoding that is used isn't obtained from the DB.  Since Java uses
unicode UCS2 internally the character set encoding is used to translate
strings from/to the DB encoding.  So it seems logical that the code
would get the encoding from the DB instead of the current method of
requiring the user pass it as a parameter.

Attached is a patch that gets the DB encoding from the DB in the same
manner as is done in libpq/fe-connect.c.  The patch is created off of
the latest CVS sources (Connection.java version 1.10).

Planner speedup hacking.  Avoid saving useless pathkeys, so that path
comparison does not consider paths different when they differ only in
uninteresting aspects of sort order.  (We had a special case of this
consideration for indexscans already, but generalize it to apply to
ordered join paths too.)  Be stricter about what is a canonical pathkey
to allow faster pathkey comparison.  Cache canonical pathkeys and
dispersion stats for left and right sides of a RestrictInfo's clause,

    attributes of each EMP instance to the temp_lo and

follows joins WEATHER to itself.

EMP is often used in Oracle examples.
