Actually, there are other messages with "server". For example, in the
AlterForeignServerOwner() or in the postgres_fdw code.
Maybe it is better to not change "server" to "foreign server" in
"create_foreign_server_if_not_exists.patch"? I think it will be better
to fix all such messages with a separate patch, If we will decide that
it is necessary to change "server" messages.
