I'm fairly sure that we've discussed allowing comma instead of dot in
regular numeric value I/O (ie, not in to_char() or other specialized
textual conversions) and explicitly rejected it as being more likely to
break things than anything else. An example of the sort of thing likely
to go wrong is that application code might not think that a numeric
value could ever need quoting to go into CSV data.
