To be clear I meant your wrapper around libpq could internally cache
this, then the call sites of users of your wrapper would not need to
be changed. i.e. your Result could contain a cache of
columnname->columnumber mapping that you know because of previous
calls to PQfnumber on the same Result.

Feel free to send a patch for this.
