Bruce-san, Tom-san, thank you for your explanation.
I understood how they avoided the situation.
We have to except patent algorithm or code like other contributing companies in PostgreSQL community.
Is that correct?
If that's yes, we can keep PostgreSQL policy.
If that's no, I might have misunderstanding, please let me know.
Best Regards,
Mototaka Kanematsu
