Oleg Bartunov has been involved in PostgreSQL development since 1996 (he introduced locale support). He is a major developer and a member of the PGDG. Together with his colleague Teodor Sigaev he developed infrastructure for implementing user-define index access methods GiST, GIN and SP-GiST, built-in full-text search facilities in PostgreSQL (formerly known as tsearch2) and a number of popular extensions like intarray, ltree, hstore, pg_trgm, jsquery and rum access method. His latest contributions are jsonb and implementation of SQL/JSON.

Oleg graduated from the Astronomy department of the Physics department at Lomonosov's Moscow State University. During his professional work at Sternberg Astronomical Institute (SAI MSU) he realized he needed a free and powerful open-source database like PostgreSQL (Postgres95 that time). Since then he extensively used PostgreSQL in his scientific work and many other projects. Oleg is an active member of Russian PostgreSQL community, he advocated the adoption of PostgreSQL by astronomical community.
