Bruce Momjian 32784cddf1 The changes I have made are described in CHANGES. This was based on
diffs to 7.3-devel and may not be applicable to 7.2. I have included a
change covered by a previous bugfix patch I submitted (the problem with
-.1 not being accepted by cube_in). It does not include a fix for the
potential buffer overrun issue I reported for cube_yyerror in
cubeparse.y.
