Hello,
recently I read
https://blog.dbi-services.com/hash-partitioning-in-postgresql-11/
and reproduced steps from the, which gave exact same count outcome,
which made me think
hashing is a pure function.
Examined the data I saw following distribution:
dept_1: 1,14,39...; dept_2: 3,11,21...; dept_3: 16,18,25...
I also found commit 1aba8e651a introducing the feature, but I'm not too
much into internals.
I wonder, could somebody write that hashing formula in pseudo-code or
point to specific place in the code, please?
Thanks,
Vlad
