Re: Advice Needed: Simultaneous Upgrade of Two-Node PostgreSQL 11 Cluster

Dears,

I hope this message finds you well.

Thank you for your support. After completing the upgrade process, we
encountered high disk IO due to queries selecting incorrect plans for
specific table. When we ran ANALYZE, it did not choose the correct plan,
likely because we are using the default ANALYZE settings, and our data size
is approximately 1.8 TB. Could you kindly provide a solution to address
this issue?

Thank you in advance for your assistance.
