Works but is too slooow. Shuffling whole table and selecting the first
row is not the way to go in this case.
Limit (cost=5340.74..5340.74 rows=1 width=4)
-> Sort (cost=5340.74..5440.70 rows=39986 width=4)
Sort Key: random()
-> Seq Scan on users (cost=0.00..2284.37 rows=39986 width=4)
Filter: (status = 'a'::bpchar)
