> The column names {{50th}} and {{90th}} are difficult to query as a selector
> or in aggregation functions since our parser expects a letter for initial
> char. It currently requires quoting like:
> {code:sql}
> SELECT table_name, "50th_ms", "99th_ms" FROM system_views.local_read_latency
> {code}
> Which is kinda difficult and non obvious, the error we give when not quoted
> also isnt that helpful. Since it is percentile a simple thing is to just ad a
> p infront:
> {code:sql}
> SELECT table_name, p50th_ms, p99th_ms FROM system_views.local_read_latency
> {code}
