Why shouldn't it have any queries at walreceiver startup? It has any
xlog segments that were copied from the master and any it can find in
the archive, it could easily reach a consistent point long before it
needs to connect to the master. If you really want to protect your
master from any additional overhead you don't currently need to
configure a streaming connection at all, you can just use the file
shipping interface.
