IIUC, isn't it enough calling a single errmsg() inside ereport() with
the prepared logmsg.data (which is a string)? The errmsg() function
will do the required translation of the logmsg.data. Why do we need
multiple errmsg() calls? Could you please elaborate a bit on how the
way currently it is done in the patch breaks localization?

+ ereport(LOG, errmsg("%s", logmsg.data));

I think that's not correct. If I'm right, the snippet pointed above is
from a perl script. In C, the strings are null terminated and they are
represented within double quotes. So we need to use double quotes for
_("on") : _("off"). And also the definition of _( ) macro points to a
function err_gettext() that expects C-style string i.e null
terminated.
