i've tried follow similar udr setup... it's not working me.

specifically, i've tried following:

mydatabase=# alter table mytable add column newcolumn character varying(50) not null default 'boo'; error:  alter table ... add column ... default may affect unlogged or temporary tables when bdr active; mytable regular table 

and this:

mydatabase=# alter table mytable add column newcolumn character varying(50); error:  no peer nodes or peer node count unknown, cannot acquire ddl lock hint:  bdr still starting up, wait while mydatabase=#
