How do you define the attribute in pgsql? I take it you cannot enter a
dimension here either.

If you just need a way to insert the data you could write your data to a
string together with the insert command so that you end up with a
string:
insert into eraDATA ( data ) VALUES('{1,2,3,....}')
This string can be executed using EXECUTE IMMEDIATE.
Or did you mean something else?
Hope this helps.
