After PostgreSQL 9.2 was released, users that relied on PostgreSQL for scale, may have noticed a performance hit. In fact, the PostgreSQL community alongside the VMware vFabric Postgres team, was able to prove that the new version demonstrated a 10% performance hit over version 9.1. As part of the VMware Postgres team, we wanted to fix this problem for our own distribution, but as mentioned in previous posts, we also wanted to contribute our fixes back to the common core. This post provides additional detail on how this problem was identified and how we worked with the open source PostgreSQL community to restore performance.
