Issue in availability GitLab Omnibus - PostgreSQL

Hi,

after setup a 5k instance with the GET I got the following issue on the GitLab Omnibus - PostgreSQL dashboard:

To fix it, I added to

avg_over_time(pg_up{job="postgres",instance=~"$instance"}[$__interval]) or avg_over_time(up{job="postgres",instance=~"$instance"}[$__interval])

the abs() command which looks like

avg(
  avg_over_time(pg_up{job="postgres",instance=~"$instance"}[$__interval]) or avg_over_time(up{job="postgres",instance=~"$instance"}[$__interval])
)

Maybe this must be added to the dashboard source?
