Are all the tablespaces connected to a single Postgres instance?

Are you still using Postgres 9.3?

Does the  Postgres top level data directory still exist?


Right, not a good day ;-)
- All tablespaces are connected to a single Postgres database instance
- I am still using Postgres 9.3 since I did not change anything related to PostgreSQL since I shut down the server a
yearago
 
- I am not sure what you mean by top level directory. 

I am using PgAdmin to access my PostgreSQL databases. I can access the default database (postgres), tablespace
definitions,group roles and login roles. The other database instance I have is the one that send me error messages.
