I'm not sure on this. There are other indexes on these table partitions as
well.
Another bit of useful info that I should have shared immediately is that
this is a monthly partitioned table, going back years. We don't drop old
partitions (yet) on this one. For now we've only added this index to a few
individual partitions. The hope was to add it to all of them and then
eventually the template (using an older version of pg_partman).
