Extended support for EXPLAIN about pghero

[ankane]

Hey @seanlinsley, I'd like to keep the interface as simple as possible and have never used any of those options personally. If any of those options help significantly, we should add them to the default.

analyze is very useful because it actually runs the given query, instead of just asking the query planner how difficult it thinks the query is. Combined with analyze, timing is also useful because it shows the actual time spent in each part of the query. Neither of which should be always-on, since people may accidentally run a query that takes minutes or hours to complete.

A simpler UI might be to include the beginning explain in the text box. Combined with a short description on the side of the different options available, I think that would be nicely usable.

FWIW, you can currently add those options to the explain text box if needed.

(ANALYZE, BUFFERS) SELECT ...

@ankane I think you should mention that in README :D
