Since you are searching by "shortname", trying adding an index on that.
Although with that tiny a table, it might not matter.
The questions are:
1. Why in the planner scanning the entire idx_listing_entrydate, when
I'd think it should be scanning the entire
pk_listingstatus_listingstatusid ?
2. Why is "Index Scan using pk_listingstatus_listingstatusid on
listingstatus listingsta1_ (cost=0.00..0.27 rows=1 width=4) (never
executed)" ?
Note: I'm new at this as well, and jumped in to learn as well as to help.
