- 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.
