Oh the use of default keyword is new to me, thanks for that.

But to make PostgreSQL more Informix-compatible, zero should have been considered as well.


1) Why? Down the road to compatibility with some undetermined group of databases lies mayhem.

2) 0 can be a valid sequence value:

test(5432)=# create sequence zero_test start 0 minvalue 0;
CREATE SEQUENCE
test(5432)=# select * from zero_test ;
 last_value | log_cnt | is_called
------------+---------+-----------
          0 |       0 | f

Then what do you do?
