Please note what the documentation says under "Partitioning Caveats".
The current partitioning support is not meant to scale past a few dozen
partitions. So the solution to your problem is to not have so many
There are plans to make some fundamental changes in partitioning
support, and one of the main reasons for that is to allow it to scale to
larger numbers of partitions. This is just in the arm-waving stage
