Comment(by pracine):

 So this should apply to: st_summarystats, st_approxsummarystats, st_count,
 st_approxcount, st_sum, st_approxsum, st_mean, st_approxmean, st_stddev,
 st_approxstddev, st_minmax (still exist??), st_approxminmax,
 _st_histogram, st_histogram, st_approxhistogram, _st_quantile,
 st_quantile, st_approxquantile, _st_valuecount and st_valuecount. Right?

 and why not: st_value ?

 One question:

 Is

 SELECT ST_ValueCount(ST_SetBandNodataValue(rast, NULL))

 as fast as

 SELECT ST_ValueCount(rast, FALSE, ...)

 ?
