That is an old version of PostgreSQL.
"intended for testing puposes only" means just that. It is a Beta release. It is not intended/advised for a production environment.
If you want the latest release, you should use 8.2.5.
What is the meaning of this on the install PostgreSQL v7.5?:
This is a pre-release version of PostgreSQL, intented for testing purposes only.
Use at your own risk!
Thanks for its quick answer,
