Give me a way to write comments in the SQL
It would be helpful if I could comment some of the fields that I'm writing with the standard postgresql comment syntax. Sometimes the queries I'm doing are going to be complicated and I'd be helpful to remember what's going on.
Actually you can already add SQL comments in the "Value selection" text area. The following is legit and will not prevent you from saving your graph and displaying it :
count(users.id) as total, -- here we count the total number of users
count(confirmed_at) as confirmed -- here we only count the confirmed users
/* And here we add a multi line comment
* to further document our select clause */
