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
