It is also important to consider the overhead of partitioning during
query planning and execution. The query planner is generally able to
- handle partition hierarchies up a few hundred 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
- <command>DELETE</command> commands. Another reason to be concerned about
- having a large number of partitions is that the server's memory
- consumption may grow significantly over a period of time, especially if
- many sessions touch large numbers of partitions. That's because each
- partition requires its metadata to be loaded into the local memory of
- each session that touches it.
