Amazon RDS for PostgreSQL adds support for the pg_bigm extension for faster full text search of languages that require multi-byte character sets such as Chinese, Korean, and Japanese.

Characters that comprise text are represented as numbers to computers. Languages such as English, French, Russian, and Hebrew use character sets of fewer than 256 characters that can be encoded in a single byte. Languages with many characters (e.g., Chinese) require more numbers, which are represented by multi-byte encoding. pg_bigm allows you to create a 2-gram (bigram) index for faster full text search of text encoded with multi-byte characters.

Amazon RDS for PostgreSQL makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. Learn more about upgrading your database instances from the Amazon RDS User Guide. See Amazon RDS for PostgreSQL Pricing for pricing details.
