Version 9.1 delivers several features which users have been requesting for years, removing roadblocks to deploying new or ported applications on PostgreSQL. These include: * Synchronous Replication: enable high-availability with consistency across multiple servers * Per-Column Collations: support linguistically-correct sorting per database, table or column. * Unlogged Tables: greatly improves performance for ephemeral data Our community of contributors innovates with cutting-edge features. Version 9.1 includes several which are new to the database industry, such as: * K-Nearest-Neighbor Indexing: index on "distance" for faster location and text search queries * Serializable Snapshot Isolation: keeps concurrent transactions consistent without blocking, using "true serializability" * Writeable Common Table Expressions: execute complex multi-stage data updates in a single query * Security-Enhanced Postgres: deploy military-grade security and Mandatory Access Control
