I was just writing some code against 1.5 and thought I might use the new .save(update_fields=['xyz']) then I realized I was using PostgreSQL - which is an MVCC... which re-writes the entire row as far as I know even when one column is being updated.
I popped into the release notes and it does in fact indicate that it is useful for high concurrency scenarios. I thought it would be nice to note in the docs somewhere that it is really not useful for database of this type unless you are using a healthy amount of the update_fields elsewhere. I might be wrong on all of this. I have never made a documentation change nor have any idea what the process would be so if someone chooses to make this note, please do! Thanks everyone!
