This new GUC allows users to select which statements are tracked by
pg_stat_monitor:
- 'top': Default, track only top level queries.
- 'all': Track top along with sub/nested queries.
- 'none': Disable query monitoring.
To avoid redudancy, now users disable pg_stat_monitor by setting
pg_stat_monitor.track = 'none', similar to pg_stat_statements.
This new GUC is an enumeration, so the pg_stat_monitor_settings view was
adjusted to add a new column 'options' which lists the possible values
for the field.
The "value" and "default_value" columns in the pg_stat_monitor_settings
view was adjusted to be of type text, so we can better display the
enumeration values. Also the boolean types now have their values
displayed as either 'yes' or 'no' to easily distinguish them from the
integer types.
Changed the default value of pgsm_bucket_time from 300 to 60. Now neither PMM users will need to adjust the default value, nor
restart of PG server will be required for this purpose.
