postgresql problmes with IMP

[Jeremy]

Hi,

I am trying a new install of IMP and horde using postgresql.  I have had a
number of problems that should go in the FAQ perhaps.  More on them later.

My present problem is :

My system is RedHat 6.2, apache 1.3.14-2.6.2
Postgres 6.5.3.6
horde-1.2.3
imp-2.2.3
php-3.0.17-1.6.2horde1 (etc - all from the horde download site)

I have installed and configured to the best of my ability :-( and got horde
sort of working with the memory store.  With postgresql I have turned on a
debug flag on the horde scripts and got the errors displayed on my IE 5.5
screen when I start up IMP

This seems like a problem in the horde program logic.  Any suggestions ?
