1. Modifying PostgreSQL Internals

• We enhance core PostgreSQL components like tablecmds.c, heapam.c, and others to:
  

  1. Speed up table creation or modification for large schemas

  2. Improve tuple handling and heap access for faster read/write operations

  3. Optimize data validation or constraint checks at the engine level

2. Custom Query Execution Behavior

• For clients managing very large datasets, we tune and alter PostgreSQL’s query planner and executor logic.
• This allows for:
  

  1. Smarter handling of JOINs, subqueries, or CTEs

  2. Customized cost estimations and parallel execution behavior

  3. Query routing adjustments to align with Odoo's specific access patterns

3. Optimizing the Storage Layer

• We implement storage-level changes that reduce I/O latency, improve cache usage, and streamline access to frequently used data.
• This includes:
  

  1. Fine-tuning page layout and compression behaviors

  2. Reducing WAL write overhead for specific workloads

  3. Implementing optimized block read strategies for large table scans

4. Enhancing Text Retrieval for Odoo

• Odoo heavily relies on large TEXT and JSONB fields (e.g., for descriptions, logs, and configurations).
• We optimize how PostgreSQL handles these data types internally — accelerating search, retrieval, and manipulation of large text blocks without increasing memory pressure or disk I/O.

5. ERP-Tailored PostgreSQL Build

• We deliver a custom PostgreSQL build specifically optimized for ERP systems like Odoo.
• This build can include:
  

  1. Performance patches relevant to business applications

  2. Pre-integrated extensions and configurations

  3. Specialized capabilities tailored to specific business needs that are not included in standard PostgreSQL.
