Rahim Kanji	d2c333dcfd	Special handling of PostgreSQL DateStyle in ProxySQL ... - DateStyle consists of two values: a format and an order (e.g., ISO, MDY). Unlike other parameters, DateStyle can be set with one or both values, and the missing value retains its previous setting. Examples: SET DateStyle TO 'ISO, MDY' → Format: ISO, Order: MDY SET DateStyle TO 'ISO' → Format: ISO, Order remains unchanged i.e MDY SET DateStyle TO 'DMY' → Format remains unchanged i,e ISO, Order: DMY SET DateStyle TO 'Postgres' → Format: Postgres, Order remains unchanged i.e DMY Improved RESET statements and DEFAULT parameter values handling - Enhance RESET and DEFAULT value handling: • When a parameter is RESET or set to DEFAULT, ProxySQL now first checks if a value is provided in the connection options. • If a connection value is specified, it is applied; otherwise, the parameter falls back to the value defined by the corresponding pgsql-default_* variable.	1 year ago

Javier Jaramago Fernández	100630fba5	Second iteration on PostgreSQL monitoring POC ... This commit packs multiple fixes/improvements: - Added READONLY support for PostgreSQL. - Major rework for queries and statements used on monitoring checks: + Checks/Actions rewrote for single instance checks. + Reuse of prepared statements instance of re-preparation. - Fixed missing error handling in connection creation state machine. - Fixed connection rotation in connection pool (now FIFO). - Added support for configurable batching in scheduler thread, via '*_interval_window' variables. These variables allows to define the burstiness of the scheduling within the processing interval. - Added new config variable 'pgsql-monitor_dbname'. Allows to control which 'db' will be target by monitoring connections. - Several fixes for 'poll' timeout computation for worker threads. - Fixed edge cases for current interval detection. - Reduced deviation in scheduling intervals computation. - Refactored and simplified connection event handling. - Improved error messages for monitoring actions. - Replaced several invalid uses of 'mysql_thread___monitor_*' in favor or new 'mysql_thread___monitor_*' variables. - Honor '-M' argument for disabling monitoring support.	1 year ago

Rahim Kanji	851a573f30	If query results needs to be cached, the pgsql_thread___query_cache_size_MB setting takes precedence over pgsql_thread___threshold_resultset_size	2 years ago
Rahim Kanji	720441af20	Refactored and Optimized Query Cache with PgSQL Support ... * Added Query Cache Support for PgSQL: * Introduced new variables for PgSQL Query Cache management: * pgsql-query_cache_size_MB * pgsql-query_cache_soft_ttl_pct * pgsql-query_cache_stores_empty_result * pgsql-query_cache_handle_warnings (not yet utilized) * Overwriting Transaction Status: * Sending current transaction state to the client when a result is returned from the query cache. * This currently does not differentiate between normal and error transaction states—both are treated as active transaction states. * Cache Lifetime Management: Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries, ensuring proper memory deallocation and reducing complexity. * Unified Purging Logic: Refactored the query cache purging logic to use a single thread for both MySQL and PgSQL cache entries. * Code Cleanup: Removed unnecessary methods and data members to streamline the codebase and improve maintainability. * Performance Optimization: Improved memory management, reducing memory footprint and enhancing performance.	2 years ago
