I think this is really nice work, so I have committed this version. I
made a few fairly minor changes, hopefully without breaking anything
in the process:
- I adjusted things for recent commits around INT{32,63}_{MIN_MAX}.
- I removed (void) ssup; which I do not think is normal PostgreSQL style.
- Removed the #if DEC_DIGITS != 4 check. The comment is great, but I
think we don't need protect against #if 0 code get re-enabled.
- I removed the too-clever (at least IMHO) handing of TRACE_SORT in
favor of just using #ifdef around each occurrence.
- I also declared trace_sort in guc.h, where various other GUCs are
declared, instead of declaring it privately in each file that needed
it.
- Changed some definitions to depend on SIZEOF_DATUM rather than
USE_FLOAT8_BYVAL. Hopefully I didn't muff this; please check it.
- Fixed an OID conflict.
- And of course, bumped catversion.
Thanks,
