Is there anything going on that might affect the time taken? - triggers,
loads of indices to be updated, etc? From the docs[1]:
no, there are no triggers at all.. just the index on the column..
can you explain what the numbers mean in the EXPLAIN ANALYZE?
(cost=0.00..8.46 rows=1 width=1073) (actual time=0.094..0.161 rows=1 loops=1)
thanks
