When installing the latest release, PostgreSQL (7.4.2 running on FreeBSD 4.10) produced a lot of syntax errors.
The table that contains the categories was not created at all.
I created the table manually but I was not able to save new entries. Again Syntax errors were the problem.
As I'm working daily with Postgres I'm very used to it!
If you like I could patch the SQL-Scripts and submit them to you. I just installed the mySQL Version (Which works very good!) and can adjust the working statements to work with Postgres.
Let me know if you want me to fix that Postgres Bugs
Greetz and keep up the good work
