"withSelect": true
This property allows returning values calculated on the fly from other infoj entries.

    "label": "Population",
    "field": "pop__17", // known value
    "type": "numeric"
},
{
    "label": "Competitors",
    "field": "comp", // known value
    "type": "integer"
},
{
    "label": "Population per competitor",
    "field": "field_withSelect", // PostgreSQL calculation result alias
    "fieldfx": "pop__17 / comp", // calcutation to perform
    "type": "integer",
    "withSelect": true
}
Each feature on this layer calculates "Population per competitor" ratio of two given values when requested.
