PostgreSQL Contributions

Committed to the
PostgreSQL community

EDB is deeply involved with and committed to the PostgreSQL community with the goal of constantly improving and building upon the software. We’re active in promoting the adoption of PostgreSQL and related software worldwide, contributing every year since 2006. Some of our team members have been involved with the project since its inception in 1996, and continue to play a key role in shaping its future.

Contributions to PostgreSQL

EDB has a long history of contributing to the growth and development of PostgreSQL. Here are just a few of our contributions:

Optimizing performance

  • Unlogged tables
  • Index only scans
  • Free space map auto-tuning
  • Heap only tuples (HOT)
  • Locking improvements for significantly better read and write scalability
  • Trigger transition tables for improved performance
  • pg_prewarm contrib module

Parallel Query

  • Parallel processing infrastructure
  • Query parallelism support for index scans, bitmap scans, merge joins, and optimizations when the data is recombined
  • Better parallel query for some UNION [ALL] cases
  • Parallel hash joins

Optimizing storage

  • Pluggable storage infrastructure
  • Crash safe and WAL enabled hash indexes
  • Materialized views

Hosting and packaging

  • StackBuilder enabling the distribution of PostgreSQL ecosystem components

But wait, there’s more!

  • ALTER SYSTEM SET command
  • Original version of the JSON data type
  • Sharding preparation with push down of joins and aggregate functions to remote servers (postgres_fdw)
