Problem with new IMP2.2.6 and horde 1.2.6

[Jaroslaw Tabor]

Hello!

	I've just installed new, updated imp 2.2.6 and horde 1.2.6 
from deb-s, from 
security.debian.org. After installation IMP stops working at all, 
displaying a lot of messages like:

Warning: 1 is not a valid PostgreSQL link resource in  
/etc/horde/db_pgsql.inc on line 52
Warning: 1 is not a valid PostgreSQL link resource in  
/etc/horde/db_pgsql.inc on line 55
.
.
....and more

I'm running:
apache-ssl 1.3.9.13-3
php4 4.0.3pl1-0potato1
postgresql 6.5.3-23

with imp 2:2.2.3-0.potato.4 and horde 2:1.2.3-0.potato.4

everything is working perfect. I tried to restart everything, reinstall 
but without success.
Can anyone help me with this ?
