Hi hackers,
I found cfbot cannot accept the v21 patch set, please see the updated version.
Recent update: I have been working on the partition stuff discussed in [1].
Initially I've firstly implemented with the approach that does the partition
routing for every changes if the target relation was the partition root, but
found it's quite an expensive: performance degraded around 30% with my micro
benchmark. Based on that, I'm thinking with the different way.
Best regards,
