Dear,

Thanks, this solved my problem. I was using very low values for
effective_cache_size.

Thanks for your attention,

Sounds like pgsql is switching to a sequential scan a little too
quickly for your dataset / server / etc...

I'd say look at increasing effective_cache_size and lowering
random_page_cost
