EXEC_BACKEND builds (i.e., Windows) failed to absorb values of PGC_BACKEND parameters if they'd been changed post-startup via the config file. This for example prevented log_connections from working if it were turned on post-startup. The mechanism for handling this case has always been a bit of a kluge, and it wasn't revisited when we implemented EXEC_BACKEND. While in a normal forking environment new backends will inherit the postmaster's value of such settings, EXEC_BACKEND backends have to read the settings from the CONFIG_EXEC_PARAMS file, and they were mistakenly rejecting them. So this case has always been broken in the Windows port; so back-patch to all supported branches. Amit Kapila
