Hmm ... I see a contributing factor here: this bit in postgresql.conf.sample is a lie: #lc_messages = 'C' # locale for system error message # strings A look in guc_tables.c shows that the actual default is '' (empty string), which means "use the environment", and that matches how the variable is documented in config.sgml. Somebody --- quite possibly me --- was misled by the contents of postgresql.conf.sample into thinking that the lc_xxx GUCs all default to C, when that's only true for the others. I think that a more correct fix for this would treat lc_messages differently from the other lc_xxx GUCs. Maybe just eliminate the hack about not substituting "C" for that one? In any case, we need to fix this mistake in postgresql.conf.sample. regards, tom lane
