Thanks for that!
I'm not sure this is related to that failure, but self-reviewing the
patch, one thing I noticed I missed is that get_steps_using_prefix()
assumes that clauses in the passed-in prefix list are sorted in an
ascending order of partkeyidx, but the caller (ie,
gen_prune_steps_from_opexps()) doesn't take that into account. I
might have broken something. I'm a bit tired today, so I'll look at
this more closely tomorrow.
Best regards,
