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

PL/Python allows you to write functions in the Python programming
|
|
language that may be used in SQL queries as if they were built into
|
|
Postgres. The PL/Python intepreter is a full Python interpreter.
|
|
|
|
PL/Python is currently only available as an "untrusted" language
|
|
(meaning it does not offer any way of restricting what users can do
|
|
in it). It has therefore been named "plpythonu". The trusted variant
|
|
plpython may become available again in future, if a new secure execution
|
|
mechanism is developed in Python.
