This is introduced by the commit 5a991ef, which allows logical
decoding via walsender interface. The paramter replication has
been there far from the commit intentionary as an 'undocumented
paramter'. This is, I suppose, because it is treated as a part of
the replication ptorocol, not a matter of ordinary clients at
all.

Since it has no meaning out of the context of replication agents,
it seems reasonable that the parameter is not documented in the
section.
Instead, the comment for libpqrcv_connect@libpqwalreceiver.c has
become outedated by the commit.

This should be synced with the document.
Thoughts?
