On the same station, i have 2 postgresql server: one for my postgis db (v9.1) and so another installed with opener^7 (9.2). Unfortunalty, i noticed i'm obliged to stop service for my postgresql postgis (9.1) in order to use openerp7 (postgres9.2). I 'm surprised about that. There is there a way to use these two servers at the same time?
What errors/information do you have when you want to run the second postgres server while the first is running?
