Default enable separate metrics for Praefect
What does this MR do?
Praefect's read-only repository metric places significant strain on
Postgres in v14.3+ and has caused a number of customer outages. To
mitigate this, the praefect['separate_database_metrics']
setting was
added, but it is currently disabled by default.
Let's enable this setting by default to help prevent future incidents.
