Documenting that queries can be run over replication protocol

Hi;

In the process of building some tooling based on replication we discovered that PostgreSQL 10 uses COPY to populate the initial table on logical replication, see commit 7c4f52409a8c7d85ed169bbbc1f6092274d03920

This is not currently documented.  Attached is a patch which adds that documentation to the logical replication part of the protocol section.

It already says earlier in that same section:

"In logical replication walsender mode, the replication commands shown
below as well as normal SQL commands can be issued."
