I upgraded from PT3 to PT4 on my iMac with no problems.
I then tried to upgrade to from PT3 to PT4 on my Macbook Pro and when I push the connect button on the Configure PostgreSQL Server box I get the following message "Unable to connect to this database. Please check the configuration."
The PostgreSQL Server Information is:
Server: localhost
database user: postgres
Port: 5432
Password: dbpass
In my applications I have folders for PostgreSQL 8.4 and 9.0.
I have seen other threads which have reported this problem but have not been able to fix this from reading them.
Your help with this will be greatly appreciated.
