I only add below:
Datum fake_dinstance2(PG_FUNCTION_ARGS) { PG_RETURN_INT16(0); } in src/backend/utils/adt/int8.c, and the I run “make install”, But I can’t find the fake_distance2 in src/backend/utils/fmgrtab.c which is generated by src/backend/utils/Gen_fmgrtab.pl. What else do I need to add?
you need to add the function metadata to pg_proc.dat
