Replace PGPROC.isBackgroundWorker with isRegularBackend.
Commit 34486b609 effectively redefined isBackgroundWorker as meaning
"not a regular backend", whereas before it had the narrower
meaning of AmBackgroundWorkerProcess(). For clarity, rename the
field to isRegularBackend and invert its sense.
Exclude parallel workers from connection privilege/limit checks.

Try to avoid semaphore-related test failures on NetBSD/OpenBSD.
These two platforms have a remarkably tight default limit on the
number of SysV semaphores in the system: SEMMNS is only 60
out-of-the-box. Unless manual action is taken to raise that,
we'll only be able to allocate 3 sets of 16 usab
Reserve a PGPROC slot and semaphore for the slotsync worker process.
The need for this was missed in commit 93db6cbda, with the result
being that if we launch a slotsync worker it would consume one of
the PGPROCs in the max_connections pool. That could lead to inability
to launch the worker, or t
