As far as I know, the CR definition of Percona PostgreSQL cluster does not provide any configuration attribute to add custom labels to the metrics sent to the PMM server from pmm-client containers.
This is possible with Percona MongoDB clusters using spec.pmm.mongodParams and spec.pmm.mongosParams, but also with Percona XtraDB clusters using spec.pmm.pxcParams and spec.proxysqlParams.
Use-Case
The additional flags, in my case custom labels, are added to the "pmm-admin add" options through the PMM_ADMIN_CUSTOM_PARAMS environment variable in the prerun script :

It would be a great feature to implement this for the Percona PostgreSQL operator as well !
Is this a feature you are interested in implementing yourself?
No
Anything else?
