Currently, the startup process ignores SIGHUP.
The attached patch allows the startup process to re-read config file:
when SIGHUP arrives, the startup process also receives the signal
from postmaster and reload the settings in main redo apply loop.
Obviously, this is useful to change the parameters which the startup
process may use (e.g. log_line_prefix, log_checkpoints).
Thanks, committed.
The fact that bgwriter can run simultaneously with the startup process
makes this more important than before. Otherwise if you change something
like log_line_prefix, bgwriter will use the new setting but startup
process will not.
