query planning and execution. The query planner is generally able to
handle partition hierarchies up a few hundred partitions fairly well,
provided that typical queries allow the query planner to prune all but a
small number of partitions. Planning times become longer and memory

but a small number of partitions. Planning times become longer and memory
consumption becomes higher as more partitions are added. This is
particularly true for the <command>UPDATE</command> and
