Most databases supporting that feature? Please give me a doc for it? Btw, I
think its okay to make a new ticket instead of reopening this.

Richard Penney commented on SPARK-21117:
This looks like a really useful feature - thanks.
However, I notice that the third version of the postgresql with_bucket()
function does not seem to have been implemented yet. This is for the,
admittedly rather more subtle, case of a user-supplied array of thresholds.
Have we decided that this partition-with-thresholds capability is not going to
be supported, or should we consider reopening this ticket?

PostgreSQL support this function:
||Function||Return Type||Description||Example||Result||
|width_bucket(operanddp, b1 dp, b2 dp, countint)|int|return the bucket number
to which operand would be assigned in a histogram having count equal-width
buckets spanning the range b1 to b2; returns 0 or count+1 for an input outside
the range|width_bucket(5.35, 0.024, 10.06, 5)|3|
|width_bucket(operandnumeric, b1 numeric, b2numeric, count int)|int|return the
bucket number to which operand would be assigned in a histogram having count
equal-width buckets spanning the range b1 to b2; returns 0 or count+1 for an
input outside the range|width_bucket(5.35, 0.024, 10.06, 5)|3|
|width_bucket(operandanyelement, thresholdsanyarray)|int|return the bucket
number to which operand would be assigned given an array listing the lower
bounds of the buckets; returns 0 for an input less than the first lower bound;
the thresholds array must be sorted, smallest first, or unexpected results will
be obtained|width_bucket(now(), array['yesterday', 'today',
'tomorrow']::timestamptz[])|2|
