I don't know what you are using as a front end to call this update, but I
have been finding json/jsonb parameters passed into a function / procedure
and then using postgres json functions to process the data as a good
solution.
If your data fits postgres array datatype, as others have mentioned, that
is also a good (and possibly simpler) solution.
