Yep, but you can do this more simply:

CREATE TABLE schema1.tbl (ID bigint default nextval('global_seq')
primary key,foo varchar,bar varchar)
CREATE TABLE schema2.tbl (ID bigint default nextval('global_seq')
primary key,foo varchar,bar varchar)

No need for the dummy table.

Obviously you would want better names than these ("global_seq" is a
really dumb name for a production environment!), but you knew that
already :)
