It queries `pg_stat_statements` to identify queries with high percent of execution time spent in JIT.
It queries the `stat_statements_jit` metric table to identify the percentage of jit in the current total query execution time within the specified grafana time window.
It queries the `stat_statements_jit` metric table to identify the percentage of jit in the current total query execution time for each dbname within the specified grafana time window.
The `Auto` option will contain a value identical to the current time range, so we can partially avoid the imprecision of `$__timeGroup()`
the minimum version where `jit_generation_time` field is available in `pg_stat_statements`.
