  1. Add a guc for parallel worker logging 

    The new guc log_parallel_workers controls whether a log message is
produced to display information on the number of workers spawned when a
parallel query or utility is executed.

The default value is `none` which disables logging. `all` displays
information for all parallel queries, whereas `shortage` displays
information only when the number of workers launched is lower than the
number of planned workers.

This new parameter can help database administrators and developers
diagnose performance issues related to parallelism and optimize the
configuration of the system accordingly.
