Shared_buffers update not showing in logs

[FinHorsley]

Hi all, apologies for a slightly broad question but trying to debug some problems we're seeing when applying changes to the postgresql conf and hitting issue with shared_buffers. Should updating the shared_buffers appear in the patch operation?

We're trying to update the max_connections, statement_timeout, and shared_buffers (all to new values), but in the logs are only seeing the max_connections and statement_timeout in the patch. Initially i thought this was because the shared_buffers couldn't be applied by just a patch, but looking at the kubernetes logs the amdb pod isn't being restarted.

time="2023-10-19T13:29:56Z" level=debug msg="patching Postgres config via Patroni API on pod database/amdb-0 with following options: 

{\"postgresql\":{\"parameters\":{\"max_connections\":\"400\",\"statement_timeout\":\"30000\"}}}" 

cluster-name=database/vqcm-amdb pkg=cluster

Exec'ing into the pod, the shared_buffers change has been applied, but there's no record of it updating in the operator logs
