syntax error wehen creating sequence

Hello,

when I create a sequence pgadmin has the tablespace listbox enable.
When I chose a tablespace then it creates the folowing command.

CREATE SEQUENCE wtb.test  INCREMENT 1  START 1  TABLESPACE pg_default;
ALTER TABLE wtb.test OWNER TO wtb;


postgres gives back a syntax error because "create sequence" does not 
allow the tablespace parameter

CREATE [ TEMPORARY | TEMP ] SEQUENCE name [ INCREMENT [ BY ] increment ]   [ MINVALUE minvalue | NO MINVALUE ] [
MAXVALUEmaxvalue | NO MAXVALUE ]   [ START [ WITH ] start ] [ CACHE cache ] [ [ NO ] CYCLE ]
 


Bye
Andreas
