Peter Eisentraut is a seasoned database engineer and open-source leader with 26 years of experience, currently serving as VP and Chief Engineer at EDB and long associated with core PostgreSQL development. He combines deep C-level systems work—contributions to PostgreSQL internals, logical replication, and extensions like pglogical—with practical tooling improvements in widely used projects such as the PostgreSQL JDBC driver, pgbouncer, and Homebrew. Peter’s background spans consulting, senior engineering, and CTO roles, reflecting both hands-on bug fixes and higher-level architectural contributions across database replication, metadata, and compatibility layers. Based in Dresden, he’s known for pragmatic fixes that improve robustness and cross-version compatibility, including bringing Oracle-compatible functions to Postgres via orafce. Colleagues rely on him for meticulous, standards-focused changes that quietly harden widely deployed systems.
