Thanks Khushboo. My apologies, but I found something else when testing.
Instead of just returning and updating the values for the key columns, we
should do it for all columns. This would have 2 benefits (and I suspect,
might actually make the code a little more simple):
1) We'd see the values for columns with default values.
2) We'd see the formatted values for other columns - e.g. with a JSONB
column, you'll immediately see what the re-generated JSON looks like.
I assume it's straightforward to update all columns rather than just the
key columns?
Thanks!
