Yes, I moved the partition bound comparison and search functions, because
I thought that they should live with the other code that manages the
cached information. So, I moved not only the code that reads the catalogs
and builds the partition key, partition (bound) descriptor, and partition
qual (for individual partitions), but also the code that uses those
So, with the new arrangement, optimizer will include utils/partcache.h,
instead of catalog/partition.h.
