1\How can I import data into my new creating DB from “my first poker database” ?I did it with "utilities-export Hand Histories To File-",but after the export is over I was always told there were some errors and no HH in the file.What is the matter? How shall I correct it.

2\How can I change the new creating DB from Access to PostgreSQL?After clicking define setting I am asked to sign in the user name /password/ODBL. What are these? Where to find them?

3\Must I Install PostgreSQL after Installed PT and PostgreSQL driver in order to use SQL DB?
