You should be able to figure that out by correlating the plan with the
original query. In this case the inner column is clearly
agg.masked_acct_id since there is nothing else that fed.masked_acct_id
would be joined to.
It's annoying that EXPLAIN isn't always able to deliver a reasonable
text representation of values that have bubbled up from a lower plan
level. I've so far not found a good fix, but it's on the to-think-about
list ...
