![“[C]ommunities are composed of individuals
who collaborate toward a common goal but
do not share a common employer
and are not governed by an
employment hierarchy.”

- 25. Open Source Development http://momjian.us/main/writings/pgsql/adoption_and_trends.pdf
- 26. We require these tools. • Revision control • Peer review • Public discussion forums
- 27. Development work • Revision control - We share our git repos: http://git.postgresql.org • Peer review - our tool for patch review: http://commitfest.postgresql.org • Public Discussion Forums - hackers list: [email protected]
- 28. Results • Yearly releases • Reputation for excellent code • Growing developer community • Reputation for rejecting patches
- 30. 9.1 beta 1 (Monday!)
- 31. Key pre 9.1 Features • Transactional DDL • Recursive queries • Built-in replication (async AND sync in 9.1) • Multiple-language support for database-side programming

- 33. Hot in 9.1! Things other databases also do: • Unlogged tables performance with ephemeral Less consistency for better data, and NoSQL buzzword compliance • Writable Common Table Expressions Recursive queries that update data • Per-Column Collations sorting words in Farsi and True multi-language support (e.g. Swedish correctly in the same table, in separate columns)
- 34. Hot in 9.1! Things we are first to do: • SE-Postgres Control integration with SE-Linux Mandatory Access • Extensions framework for easily installing, CREATE EXTENSION removing and updating extensions to Postgres. And launch of PGXN network: http://pgxn.org
- 35. Hot in 9.1! Things we are first to do: • Synchronous replication to prevent data loss. Create synchronous standby databases Includes "transaction-controlled synchronous commit" • SQL-MED data source access that enables Easy-to-use remote transparent usage as a table (SELECT and JOIN) • K-Nearest-Neighbor Indexing Permits doing an indexed search of "what's near me".
- 36. We still have bugs. We still have an epic todo list. We still need people of every ability.
- 37. So, how do you get involved?
- 38. Download 9.1 Beta 1! (on Monday)
- 39. Commitfest tool http://bit.ly/pgdevnow
- 40. Volunteer. Blog, answer email, join #postgresql, write documentation, test features, make things with Postgres, tweet, help organize meetings, create olypug, give a talk, do a translation...
- 41. Change the world with us.
