I have installed an independent postgresSql version 9.1 (x86). Then i simply had installed odoo-11 service without the postgresql because i already have it. After that I had to download the odeo11 source code and configure it in pycharm here is the screen shot of my odoo configuration.I had used different postgresql user for each odoo version.
here is my odoo.conf
[options]
; This is the password That Allows database operations:
; admin_passwd = admin
db_host = localhost
db_port = 5432
db_user = openpg
dbfilter =odoo11
db_password = openpgpwd
addons_path = d: \ odoo \ addons
xmlrpc_port = 8088
Futher i had debugged with pycharm and i was successfull in installing odoo-11
But i had installed odoo10 using same method then my odoo11 install got conflicted with odoo11 and console shows me error
Skipping database pos10 as its base version is not 11.0.1.3
But my odoo10 is working fine now. here is my odoo.conf of odoo10
[options]
; This is the password that allows database operations:
; admin_passwd = admin
db_host = localhost
db_port = 5432
db_user = openpg1
dbfilter=odoo10
db_password = 123
addons_path = D:\odoo-10.0\odoo-10.0\addons
xmlrpc_port = 8080
here is the configuration of odoo10 instance
