Re: Catalog domain not-null constraints

create domain connotnull integer;
create table domconnotnulltest
( col1 connotnull
, col2 connotnull
);
alter domain connotnull add not null value;
---------------------------
the above query does not work in pg16.
ERROR: syntax error at or near "not".

after applying the patch, now this works.
this new syntax need to be added into the alter_domain.sgml's synopsis and also
need an explanation varlistentry?
