Summary: PgSQL.Cursor.__fetchManyRows shoud use xrange

Initial Comment:
In PgSQL.Cursor.__fetchManyRows range(count) may
generate a huge list, if a large count is used. (This
happens in combination with ZpyPgSQLDA.db.DB.query with
no max_rows set (Its default is 9999999!))

Maybe using xrange can help, it speeds things
daratically up.
(see also
http://www.python.org/doc/current/lib/built-in-funcs.html#l2h-73
)
So I attached a patch to use xrange instead of range.
