Hi Andrey, This looks really interesting, and I am sure there are a lot of GIS people who would love to see dramatically faster and smaller indexes in PG13. I don't know enough to comment on the details, but here are some superficial comments: + method is also optional and is used diring fast GiST build. -> during + /* esteblish order between x and y */ -> establish +/* Compute Z-oder for point */ static inline uint64 point_zorder_internal(Point *p) -> order Could this function please have a comment that explains why it works? I mean, just a breadcrumb... the name of the technique or something... so that uninitiated hackers can google their way to a clue (is it "Morton encoding"?) MSVC says: src/backend/access/gist/gistproc.c(1582): error C2065: 'INT32_MAX' : undeclared identifier GCC says: gistbuild.c: In function ‘gist_indexsortbuild’: gistbuild.c:256:4: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement] IndexTuple *itvec = gistextractpage(lower_page, &vect_len); ^
