Thanks for the suggestion.  I tried that but NonReservedWord_or_Sconst
conflicts with Sconst that partbound_datum itself has a rule for,
resulting in the following error:

gram.y: conflicts: 6 reduce/reduce
gram.y: expected 0 reduce/reduce conflicts
gram.y:2769.25-81: warning: rule useless in parser due to conflicts:
partbound_datum: Sconst

Moreover, it seems like on/off are not being accepted as valid Boolean
values like true/false are.

insert into rp values (true);
INSERT 0 1
insert into rp values (on);
ERROR:  syntax error at or near "on"
LINE 1: insert into rp values (on);
                               ^
What's going on with that?   Maybe on/off values work only with SET
statements?

Thanks,
Amit
