I'm building against 9.6.3 on both machines. I'm not doing anything
special to change the compilation options. Here is my whole Makefile:
MODULES = floatfile
EXTENSION = floatfile
EXTENSION_VERSION = 1.0.0
DATA = floatfile--$(EXTENSION_VERSION).sql
PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
But what I'm really interested in is this: What are the bad things
that can happen if I do `datums = (Datum *)floats`, as long as it's
only when Datums are 8 bytes wide? Is there a platform with
pass-by-val float8s where that won't work?
Thanks,
Paul
