I like the idea of reducing duplication.  I don't like the "prefix"
as proposed though, because it's not going to work well for translation
(string building) -- I'd rather pass the entire phrase from caller, so
that the translator has one piece to translate which lives in the module
that emits it.  I think I'd do something like

    ereport(LOG,
            errmsg_internal("%s: %.*s",
                        _(prefix), len, message));

and see to it that each caller uses gettext_noop() around the string
they pass as "arg", for gettext to collect.
