Well, that was a bit better than I expected.  While the overall code
coverage for PostgreSQL source code is:
 
Overall coverage rate:
  lines......: 64.8% (130296 of 201140 lines)
  functions..: 72.0% (7997 of 11109 functions)
 
The coverage for predicate.c, after running both check and dcheck,
was (formatted to match above):
 
  lines......: 69.8% (925 of 1325 lines)
  functions..: 85.7% (48 of 56 functions)
 
Most of what was missed was in the SLRU or 2PC code, which is
expected.  I'll bet that the DBT-2 runs, between the "normal"
and TEST_OLDSERXID flavors, would get us about 2/3 of the way from
those numbers toward 100%, with almost all the residual being in
2PC.
 
Does anyone have suggestions for automated 2PC tests?
