I have exactly the same problem ...

I have the PEAR::DB correct (I guess),

I do pear info DB and I see it is correctly installed on version  1.7.6



In relation to the DB user i think it s ok. How can I test easily if a 
user can create a sequence??

Either your database user doesn't have permission to create sequences, 
or you have some bug in PEAR::DB that's unrelated to Horde.

Hello,

I had setup latest version of horde, imp abd turba with Postgres 
backend on Fedora C3. All works fine...



Then I tried to setup kronolith...

these are the messages I got in my horde log:



Jun 04 11:19:02 HORDE [error] [kronolith] DB Error: unknown error:

Thanks in advance for any suggestion.
