I got the following error with k8s 1.26.

I think that's cause PodDisruptionBudget got ripped out and we need to update the version of the operator to handle it.

This seems to have been fixed here: https://github.com/percona/percona-xtradb-cluster-operator/commit/b2f71dba8e31d4d26bb91f9ddd17224b16e1803d

[mnaser]

We should bump the operator to 1.12

[okozachenko1203]

pxco 1.12 generates policy/v1 PDBs without a doubt for new clusters. But for existing ones, it doesn't upgrade automatically and just output the following warns in its log stream

W0705 12:32:57.828004       1 warnings.go:67] policy/v1beta1 PodDisruptionBudget is deprecated in v1.21+, unavailable in v1.25+; use policy/v1 PodDisruptionBudget
