It adds a WITH OIDS option to the copy command, which allows
dumping and loading of oids.

        If a copy command tried to load in an oid that is greater than
its current system max oid, the system max oid is incremented.  No
checking is done to see if other backends are running and have cached
oids.

        pg_dump as its first step when using the -o (oid) option, will
copy in a dummy row to set the system max oid value so as rows are
loaded in, they are certain to be lower than the system oid.

        pg_dump now creates indexes at the end to speed loading

Previously Postgres95 wouldn't accept 'order by' clauses with fields
referred to as '<table>.<field>', e.g.:

        select t1.field1, t2.field2 from table1 t1, table2 t2
                order by t2.field2;

This syntax is required by the ODBC SQL spec.

While a normal SELECT statement can contain a GROUP BY clause, a cursor
declaration cannot. This was not the case in PG-1.0. Was there a good
reason why this was changed? Are cursors being phased out? Is there any way
to get data with just a SELECT (and without a DECLARE CURSOR ...)?

The patch below seems to fix things. If anyone can see a problem with it,
please let me know. Thanks.
