Integrating PostgreSQL with Odoo: A Guide
Odoo, a popular open-source ERP (Enterprise Resource Planning) system, uses PostgreSQL as its default database management system. This article provides a detailed guide on setting up and managing PostgreSQL with Odoo, including examples and explanations to help you effectively use this powerful combination.
How PostgreSQL works with Odoo?
Setting Up PostgreSQL for Odoo
Prerequisites:
Step 1: Install PostgreSQL
Using Ubuntu:
# Update the package list sudo apt update # Install PostgreSQL sudo apt install postgresql postgresql-contrib
Step 2: Create a PostgreSQL User for Odoo
Odoo requires a database user with specific permissions.
# Switch to the PostgreSQL user sudo -i -u postgres # Create a new PostgreSQL user for Odoo createuser -s odoo_user # Set a password for the new user psql \password odoo_user
Explanation:
Step 3: Configure Odoo to Use PostgreSQL
Update the Odoo configuration file (odoo.conf) to include PostgreSQL connection details.
Example odoo.conf File:
Code:
[options]
db_host = localhost
db_port = 5432
db_user = odoo_user
db_password = your_password
addons_path = /path/to/odoo/addons
Explanation:
Step 4: Create a Database for Odoo
You can create a database directly via Odoo’s web interface or using the createdb command.
Command-Line Method:
Code:
createdb -O odoo_user odoo_db

Example Query Using Odoo ORM with PostgreSQL
Odoo’s ORM allows you to interact with PostgreSQL without writing raw SQL queries. Here’s an example in Python:
Code:
# Import Odoo ORM modules
from odoo import models, fields
class Product(models.Model):
_name = 'product.product'
name = fields.Char(string='Product Name')
price = fields.Float(string='Price')
# Query products using ORM
products = self.env['product.product'].search([('price', '>', 100)])
for product in products:
print(f"Product: {product.name}, Price: {product.price}")

Best Practices for Managing PostgreSQL with Odoo
1. Regular Backups: Use tools like pg_dump or automated scripts to back up the Odoo database.
2. Index Optimization: Analyze and optimize indexes for frequently queried data.
3. Connection Pooling: Use connection pooling to manage multiple Odoo users efficiently.
4. Database Monitoring: Monitor database performance using tools like pgAdmin or Prometheus.
