Replace PGPROC.isBackgroundWorker with isRegularBackend.
Commit34486b6 effectively redefined isBackgroundWorker as meaning"not a regular backend", whereas before it had the narrowermeaning of AmBackgroundWorkerProcess(). For clarity, rename thefield to isRegularBackend and invert its sense.Discussion:https://postgr.es/m/1808397.1735156190@sss.pgh.pa.us
