Subject: [PATCH] Fix mishandling of background worker PGPROCs in EXEC_BACKEND
builds.
InitProcess() relies on IsBackgroundWorker to decide whether the PGPROC
for a new backend should be taken from ProcGlobal's freeProcs or from
bgworkerFreeProcs. In EXEC_BACKEND builds, InitProcess() is called
sooner than in non-EXEC_BACKEND builds, and IsBackgroundWorker wasn't
getting initialized soon enough.
Report by Noah Misch. Diagnosis and fix by me.
