The value of the flux field on SpectroscopyReducedDatum is unbounded, which makes it unsuitable for use in a unique index. This changes the index such that the md5 of the field (after converting it to text) is used instead.

The value of the flux field on SpectroscopyReducedDatum is unbounded, which makes it unsuitable for use in a unique index. This changes the index such that the md5 of the field (after converting it to text) is used instead.
The resulting index looks like this in postgres:
"unique_spectroscopy" UNIQUE, btree (target_id, "timestamp", telescope, instrument, md5(flux::text), reduction_version)
