Though I've not reviewed the patch deeply yet, I observed the following
two problems when I tested the patch.
When I set up streaming replication + archive (i.e., restore_command is set)
and started the standby, I got the following error:
FATAL: all AuxiliaryProcs are in use
LOG: walrestore process (PID 18839) exited with exit code 1
When I started an archive recovery without setting restore_command,
it successfully finished.
