What do you mean by VM? Is this a virtualized environment or bare hardware?
Yes, they are virtualized environments.
Sorry about the confusion. But I was just telling from based on the explain
plan report. e.g at the bottom of explain plan report it says "Total
runtime: 1698.453 ms" (This is with analyze option).
But from the client perspective (either run from pgadmin or directly from
the server command line) it takes more that 20 min to display the output.
