Operator admissionwebhook validation fail

I have this weird issue where I cannot apply any changes or even kubectl diff a SGCluster.yaml definition to any clusters. For example, if I run kubectl diff -f myCluster.yaml for a cluster that exists, I get the following error from Stackgres Operator:

Error from server (https://stackgres.io/doc/1.16/api/responses/error#forbidden-configuration-update): error when patching "myCluster.yaml": admission webhook "sgcluster.validating-webhook.stackgres.io" denied the request: to upgrade a minor Postgres version, please create an SGDbOps operation with "op: minorversionUpgrade" and the target postgres version.

The odd thing is that when I run kubectl diff, it is on a SGCluster definition that is exactly the same as the currently installed/deployed one. I am not at all attempting to do a minor version upgrade. Moreover, this is the full stacktrace from the operator pod:

ERROR [io.st.op.va.ClusterValidationResource_Subclass] (executor-thread-1268) cannot proceed with request ac109ca1-7865-4bf8-88da-ec0a351cb3c6 cause: to upgrade a minor Postgres version, please create an SGDbOps operation with "op: minorVersionUpgrade" and the target version.: io.stackgres.operatorframework.admissionwebhook.validating.ValidationFailed: to upgrade a minor Postgres version, please create an SGDbOps operation with "op: minorVersionUpgrade" and the target postgres version.

For the record, this probably happened after I upgraded my Stackgres operator from 1.14.1 -> 1.16.3. I have already applied security upgrade to all my Postgres cluster, so that kubectl get sgclusters --all-namespaces -o jq | jq '.items[].metadata.annotations."stackgres.io/operatorVersion"' returns "1.16.3" for all clusters.

I have not attempted to uninstall and re-install the Stackgres operator. Is this safe to do, when I have three Postgres clusters running? I cannot risk losing any data. If so, is it as simple as doing a helm uninstall [...] and then helm upgrade --install [...]?

Stackgres operator version: 1.16.3

Postgres cluster version: 16.4

K8s version: v1.30.9+k3s1

Any help here is appreciated!
