The EXPLAIN ANALYZE shows that it's using an INDEX and getting one
row! So I know the SQL is right.
Could it be that the SQL queries become slow because some other
background operation is running, like pg_dumpall or vaccuum? How would
I test this hypothesis if the log does have mentioned of "vaccuum
analyze" being slow?
