Generalises tests for all the different drivers.
Run the general test for the various drivers.
This allows support for parallel testing as the tests now do not rely on the same DB file.
There is a PostgreSQL account for the users running the test scripts
There is database named test
For instance, if your login name is testuser, you should have PostgreSQL user
account named testuser and grant that user access to the database test.
If you have account and database, type createdb test from command prompt to
create the database to execute the test scripts. By executing the above command
as the same user running the tests you ensure that the user is granted access to
the database.
If you find problems in PostgreSQL extension, please report a
bug.
