So here's the latest (and, hopefully, last) version:
- adds diagnostic output from numeric_abbrev_abort using the trace_sort
GUC
- fixed Datum cs. uint32 issues in hash_uint32
- added a short comment about excess-k representation
- tweaked the indenting and comments a bit
I'm not particularly committed to any specific way of handling the
DEC_DIGITS issue. (I moved away from the "transparently skip
abbreviations" approach of the original because it seemed that reducing
#ifdefism in the code was a desirable feature.)
The INT64_MIN/MAX changes should be committed fairly soon. (I haven't
posted a patch for TRACE_SORT)
