[Koha] Postgres 8.2 Support for koha.

Hai All, I am trying koha 3.0 on ubuntu 8.04 with postgres 8.2. For installation, i refered http://wiki.koha.org/doku.php?id=koha_3_install_guide_ubuntu_hardy which is very useful. During Installation, database didn't create by the installation script. So i created it manually. And find some tables are missing in the postgres database script. i refered the table structure for mysql and created. Installation moved smoothly. and i logged into the koha library. I tried to create a patron and catalogue, set a library. These modules give me error production mode - trapped fatal error. Anyone please tell me whether postgres support is there for koha? With Kind Regards, K.Dinesh
