pgpointcloud doesn't compile against PostgreSQL 15beta1

[robe2]

I ran into two issues compiling pgpointcloud under mingw64 with PG15. 1) First is macro expansion doesn't handle beta. 2) pg_atoi was removed in PG15.

Take a look at https://github.com/MobilityDB/MobilityDB/issues/218

I'll take a stab at patching these up later if not addressed yet.

I realized I was compiling against tagged. So there is only one issue the pg_atoi one. I'm testing out patch now for that and will do a pull request shortly.
