Comment (by nilason):

 `pointcloud` uses for parts of its build, configuration from PostgreSQL,
 derived by including `pg_config --pgxs`  (the configurations of interest
 is ultimately read from
 `${prefix}/lib/postgresql15/pgxs/src/Makefile.global`). According to Port
 health at https://ports.macports.org/port/pg15-pgpointcloud/details/, this
 is working out fine for all OS with results. The C++ standard part is
 surely easily implementable, but I have no idea of how to address the
 second part of the ticket.
