In the following comment, it's better to change "wal sender process"
to "walsender" to follow the modified name.

-     * postgres: wal sender process <user> <host> <activity>
+     * postgres: walsender <user> <host> <activity>     *     * To achieve that, we pass "wal sender process" as
usernameand
 
username     * as dbname to init_ps_display(). XXX: should add a new variant
of     * init_ps_display() to avoid abusing the parameters like this.     */

"WAL writer process" is used, not "walwriter", is used in postmaster.c
as follows.  I guess this is for natural language.  Is this intended?
I'm OK with either, though.
               HandleChildCrash(pid, exitstatus,                                _("WAL writer process"));
           case WalWriterProcess:               ereport(LOG,                       (errmsg("could not fork WAL writer
process:
%m")));


Personally, I prefer "wal writer", "wal sender" and "wal receiver"
that separate words as other process names.  But I don't mind leaving
them as they are now.  I'd like to make this as ready for committer
when I get some reply.
