[Postgres-xc-general] (Global) nextval() from sequences support

[David H. <dav...@me...>]

After playing around with postgres-xc 0.9.5, I wanted to give my actual 
application a try. I get the following error message when setting up the 
base schema: "ERROR:  Postgres-XC does not support DEFAULT with 
non-immutable functions yet". This happens when setting up a column as 
follows (this is btw copied verbatim from the postgresql documentation, 
explaining how a serial type works):

CREATE SEQUENCE tablename_colname_seq;
CREATE TABLE tablename (
     colname integer NOT NULL DEFAULT nextval('tablename_colname_seq')
);
ALTER SEQUENCE tablename_colname_seq OWNED BY tablename.colname;

I've read that (global) sequences and serial are not yet supported. I 
checked the roadmap and couldn't find mention of this explicitly. I was 
wondering if support is planned, and if so, when? (And if not, why :-).

Thanks,
David
