Planner-list Error when connecting to the db

[Ulf Renman <ulf renman favoptic com>]

Hi

I have resiliently started to use planner and is very satisfied with how 
it works so far. But now I would like to store the data in a db to share 
it with my colleagues in a convenient way. But I get some errors that I 
do not understand exactly, could someone point me in the right direction?

* I run Planner 0.14.3 on Ubuntu 8.10
* I have created the db, user and group and made it accessible by
 configuring pg_hba.conf (postgres 8.3)
* I have tried to save both before creating the tables and after 
creating them with the provided database.sql file
* When starting planner from console I get the following output when I 
try to File->Export->Save to Database:
------------------
Error: Could not find provider PostgreSQL in the current setup

** (planner:19838): CRITICAL **: gda_connection_add_event: assertion 
`GDA_IS_CONNECTION (cnc)' failed

(planner:19838): GLib-WARNING **: GError set over the top of a previous 
GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL 
before it's set.
The overwriting error message was: Datasource configuration error: could 
not find provider 'PostgreSQL'
Error: Could not find provider PostgreSQL in the current setup

** (planner:19838): CRITICAL **: gda_connection_add_event: assertion 
`GDA_IS_CONNECTION (cnc)' failed

(planner:19838): Planner-WARNING **: Can't connect to database server in 
order to check/create the database: HOST=localhost;DB_NAME=plannerdb
------------------

Thanks
