support JSONB subscripting syntax

support JSONB subscripting syntax

Added support for PostgreSQL 14+ JSONB subscripting syntax. When connected
to PostgreSQL 14 or later, JSONB columns now automatically use the native
subscript notation ``jsonb_col['key']`` instead of the arrow operator
``jsonb_col -> 'key'`` for both read and write operations. This provides
better compatibility with PostgreSQL's native JSONB subscripting feature
while maintaining backward compatibility with older PostgreSQL versions.
JSON columns continue to use the traditional arrow syntax regardless of
PostgreSQL version.
