The PSCS RAW converter will extrapolate missing highlight information
in one channel based on that in other channels, according to Adobe.
Based on considerable personal experience, I can say that I've seen
highlights "appear" when the exposure is dialed down in conversion that
were at not apparent at first viewing. I also know I can pull up
underexposed parts of a frame in RAW if I expose to save the
highlights. In other words I can manipulate the exposure curve, post
exposure.
I realize the stars are due to diffraction, but the poster (was it
you?) also complained about flare with 35mm. I merely pointed out that
flare is a function of lensing.

No, it doesn't. Once the sensor is saturated no RAW format in the
world
will bring back the lost infirmation.
For extreme situations, it's easy to marry two exposures.
Only with static subjects.
Controlling flare is mainly a lensing
issue. The most current Pentax glass, such as the FA 35/2, can handle
situations like you show here without flare.
Those stars aren't flare but the result of diffraction at the diaphragm
edges.
