Details:

hi,

we would like to have convinience data conversion from datatype number of
value '' as null and datatype date / timestamp / timestampz of value '' as
null...

so far, postgresql will reject those value for number and date / time field
when it's empty string '' (as invalid date value or invalid number value)

it would be nice to have it auto converted :)
