Yes, please, let's do it here.

No, this doesn't work.  When the first word is something that is
not to be translated (a literal parameter name), let's use a %s (but of
course the values must be taken out of the phrase too).  But when it is
a translatable phrase, it must be present a full phrase, no
substitution:

	pg_log_error("%s must be in range %s..%s", "extra_float_digits", "-15", "3");
	pg_log..("compression level must be in range %s..%s", "0", "9"))

I think the purity test is whether you want to use a _() around the
argument, then you have to include it into the original message.

Thanks
