PostgreSQL installation/setup problem

Had this issue. Followed, other peoples advice, but had to also delete the thingworx tablespace. 

to do that:

In pgAdmin

 -From the Browser (left pane) 

- Expand Servers - PostgreSQL - Table spaces

- Delete the thingworx tablespace

Try the script again

thingworxPostgresDBSetup.bat -a postgres -u twadmin
