ProxySQL v3.0.0-Alpha Release Notes

Release date: 2024-09-23

We are excited to announce the release of ProxySQL v3.0.0-Alpha. This major version introduces PostgreSQL support as its primary feature, along with numerous improvements, bug fixes, and optimizations.

Major Features

PostgreSQL Support

  • Implemented support for PostgreSQL, enabling ProxySQL to act as a proxy for both MySQL and PostgreSQL databases. Default ports for PostgreSQL: 6132 for admin portal and 6133 for PostgreSQL backend.
  • Added Plain Text and MD5 and SCRAM-SHA-256 authentication method for PostgreSQL.
  • Introduced PostgreSQL-specific configuration options and tables.
  • Introduced SSL connection support for both PostgreSQL frontend and backend connections.
  • Implemented multiplexing for PostgreSQL.
  • Enabled connection reuse from the connection pool.
  • Added support for executing multiple statements within a single query.

Improvements and Optimizations

Query Processing and Performance

  • Refactored Query Processor Architecture, introducing separate query processors for MySQL and PostgreSQL.
  • Improved handling of malformed packets and transaction detection.
  • Optimized buffer functionality in PgSQL_Query_Result.
  • Enhanced the performance of the packing process.

Configuration and Administration

  • Added new variables for PostgreSQL:

      Default authentication method is SCRAM-SHA-256 (3)

    • pgsql-default_client_encoding: Specifies the default client encoding to be used if the client does not provide one.
      Default client encoding is ‘UTF8’

  • Added multiple new tables for PostgreSQL configuration:

    • pgsql_servers and runtime_pgsql_servers
    • pgsql_users and runtime_pgsql_users
    • pgsql_query_rules and runtime_pgsql_query_rules
    • stats_pgsql_client_host_cache

      • Implemented SHOW PGSQL PROCESSLIST command.
      • SHOW FULL PROCESSLIST and SHOW PROCESSLIST commands will continue to function for MySQL.
    • stats_pgsql_query_digest
    • stats_pgsql_query_digest_reset
    • stats_pgsql_query_rules

Monitoring and Debugging

  • Added new statistics tables for PostgreSQL connections and queries:
  • Improved error logging and debugging capabilities.
  • Introduced new timers for debugging purposes in Base_Thread.

Known Issues:

  • Prepared Statements and COPY in binary format: These features are not yet supported for PostgreSQL. This limitation will be addressed in future updates.

Upgrading

ProxySQL v3.0.0 is an alpha release and must not be used in production environments. This version is intended for testing and evaluation purposes only.

When testing ProxySQL v3.0.0, please note that this is a major version release and contains significant changes, particularly the addition of PostgreSQL backend support. We strongly encourage users to:

  1. Test thoroughly in isolated, non-production environments.
  2. Report any bugs or issues encountered during testing.
  3. Provide feedback on the new PostgreSQL support feature.

Do not attempt to upgrade production environments to this alpha release. Continue using the latest stable version for production workloads.

We appreciate your help in testing and improving ProxySQL. Your feedback during this alpha phase is crucial for ensuring the stability and reliability of future releases.
