> In SQL, it's possible to define default values for some columns. These values
> would be used on insertion when explicit values are omitted. For example:
> {code:sql}
> sql-cli> create table def_time(key INTEGER not null, val TIME not null
> default '12:12:12', primary key (key));
> sql-cli> insert into def_time (key) values (1);
> sql-cli> select * from def_time;
> ╔═════╤══════════╗
> ║ KEY │ VAL ║
> ╠═════╪══════════╣
> ║ 1 │ 12:12:12 ║
> ╚═════╧══════════╝
> {code}
> But it's not true for *UUID* data type. It's possible to "define" default
> value for this type, but it's not actually applied as default:
> {code:sql}
> sql-cli> create table def_uuid(key INTEGER not null, val UUID not null
> default '4a2f1859-c73b-4eec-a29c-629ec68d8735', primary key (key));
> sql-cli> insert into def_uuid(key) values (1);
> Unknown error
> null
> {code}
> Only explicit UUID values are currently supported:
> {code:sql}
> sql-cli> insert into def_uuid values (2,
> '46e438c5-4722-4806-8614-e5aa15b9ded8');
> Updated 1 rows.
> sql-cli> select * from def_uuid;
> ╔═════╤══════════════════════════════════════╗
> ║ KEY │ VAL ║
> ╠═════╪══════════════════════════════════════╣
> ║ 2 │ 46e438c5-4722-4806-8614-e5aa15b9ded8 ║
> ╚═════╧══════════════════════════════════════╝
> {code}
> Found on `06f62ebd7abb76f9c24d171cf03bad26f21436ca`.
> Probably, it's simply a non-implemented-yet feature (as UUID-related epic is
> not completely finished yet). In that case, feel free to trasnform this
> ticket from bug into a feature request.
