We do not need extra line
   <variablelist>
+
+  <varlistentry>
other usages of this do not have an extra line. Removed the extra line
in the attached patch.

I noticed that the earlier error message was using "server" instead of
"foreign server", while the new message uses the later one. Usually,
when converting an error to notice, we don't expect such changes. But
many other error messages are using "foreign server" instead of
"server", so probably this one needed a change anyway. But then, the
command to create a foreign server is not "CREATE FOREIGN SERVER",
it's "CREATE SERVER", so users are already getting confused?

I don't see similar change in the error message for the user mapping.
Do we need to change "server" to "foreign server" in case of user
mapping?  The doc changes didn't compile with error
"osx:ref/create_user_mapping.sgml:52:15:E: document type does not
allow element "VARLISTENTRY" here; assuming missing "VARIABLELIST"
start-tag". The user mappings do not have name so the doc change was
slightly incorrect when it said "Do not throw an error if a user
mapping with the same name already exists.". I have corrected both
these things in the attached patch.

Other changes look good.
