I'd propose to remove an assertion causing this (and the outer_binfo/inner_binfo variables) from partition_bounds_merge(), rather than doing so, because the assertion is redundant, as we have the same assertion in merge_list_bounds() and merge_range_bounds(). Please find attached a patch.
Oh, I didn't see this mail before sending my other mail.
I think it's better to have the assertion in all the three places and also in merge_hash_bounds() whenever that comes along. The assertion in merge_*_bounds() will be good to in case those functions are called from places other than partition_bounds_merge(). The assertion in partition_bounds_merge() will make sure that when the individual merge_*_bounds() functions are called based on one of the bounds both of the bounds have same strategy.
