Maybe it would be easier to deal with this by passing around a struct
with keyword/value pairs that can be given to PQconnectdbParams (and
keeping dbname as a param that's passed separately, so that it can be
added when one is needed), instead of messing with the string conninfos;
then you don't have to worry about quoting.
