Add a SHOW command to the replication command language.
This is useful infrastructure for an upcoming proposed patch to
allow the WAL segment size to be changed at initdb time; tools like
pg_basebackup need the ability to interrogate the server setting.
But it also doesn't seem like a bad thing to have independently of
that; it may find other uses in the future.
Robert Haas and Beena Emerson. (The original patch here was by
Beena, but I rewrote it to such a degree that most of the code
being committed here is mine.)
