158695: kvnemesis: treat pg replica unavailable as an unavailable error r=iskettaneh a=iskettaneh

This commit expands the condition where we expect a replica unavailable to include pg replica unavailable errors. This will apply to SQL requests that hit things like the leaderless watcher due to a known unavailability

Fixes: #158683
