It seems like for user and database it might be sensible to apply
PQescapeIdentifier to the value before printing it.  This will
double-quote it and escape any internal double-quotes appropriately.
The port is, I guess, being stored as a string, but doesn't it have to
be an integer?  In which case, why quote it at all?

Is there really a point to the non-DSN format or should we just use
the DSN format always?
