About

Oleg Bartunov, a major PostgreSQL developer, has been involved in PostgreSQL development since 1996 ( he introduced locale support). He is one of the author of the PostgreSQL extendability infrastructure (GiST, GIN, SP-GiST) and several popular non-atomic data types, such as, arrays, full text search, NoSQL (hstore and jsonb). His latest contribution is a new access method RUM, which greatly improves full text search.

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. One of his scientific projects make use of scalable indexing of multi-terabytes sky catalogues developed for PostgreSQL, which outperforms known techniques used in commercial databases.

His main interests are Informaton Retrieval, Databases Extensibility, Algorithms and Data Structures, Service-Oriented Architecture for Science and XLDB for Science. In spare time he like to play volleyball, running and trekking in Himalaya.
