Could be. The actual standard use of SIGTERM is to kill processes
belonging to your terminal process group when you log out. So, for
example, manually starting the postmaster from a terminal window and
then closing that window could cause this to happen.
I suppose the OP is bright enough to have noticed the connection between
closing the window and losing the postmaster, so it's probably not quite
that simple, but anyway something like this is what to look for.
