OK,I seem to have gotten the answer for the question
   Is tablespace defined per PostgreSQL's database ?

You and Bruce
   1) tablespace is per database
Peter seems to have the following idea(?? not sure)
   2) database = tablespace
My opinion
   3) database and tablespace are relatively irrelevant.
       I assume PostgreSQL's database would correspond 
       to the concept of SCHEMA.

It seems we are different from the first.
Shoudln't we reach an agreement on it in the first place ?
