I tried to use the database doc:

https://pagure.io/koji/blob/master/f/docs/source/database_howto.rst

but the actually script to copy existing data to partitions errored out:

SQL Error [42601]: ERROR: syntax error at or near "PARTITION"

I think that syntax is introduced in postgresql 10? Perhaps the doc could talk a bit about versions? what the lowest version expected is, what version is needed for partitioning, ,etc?
