datadir stats are not accessible by node_exporter in PostgreSQL pods

Description

Hi,

It looks like in the pmm-client sidecar the datadir mountpoint is not access by node_exporter because it is not exposed in the /proc

Compared with PXC pods, the sidecar can see the mountpoint in/proc.

Please expose the datadir to the sidecar so the node_exporter can gather the metrics.
