I took a stab at this. I think rearranging the code in
make_partitionedrel_pruneinfo() slightly will take care of this.
The problem is that make_partitionedrel_pruneinfo() does some work which
involves allocating arrays containing nparts elements and then looping
over the part_rels array to fill values in those arrays that will be used
by run-time pruning. It does all that even *before* it has checked that
run-time pruning will be needed at all, which if it is not, it will simply
discard the result of the aforementioned work.
Patch 0008 of 0009 rearranges the code such that we check whether we will
need run-time pruning at all before doing any of the work that's necessary
for run-time to work.
Yeah, this is better :) Increasing number of partitions leads to a TPS
within the noise level.
Passes check-world.
Best regards,
