"columns" is a STRING, so in theory there are (other) cases that more than
two parameters can be listed, e.g. the SQL statements.

Question: could we add in the parser something like

opt->pairanswer = YES|NO,

and enforce pairs in case of YES? This would be useful as well
for east_north coordinates and such. Default NULL/NO for compatibility.

?

Dunno if we can change the struct (yet another API change?),
