My output of explain (analyze,buffers) is something like this:
shared hit=3796624 read=46038
So what is meant by *read* here? Does it indicates number of disk reads?
Does *shared hit* takes into account only the hit in the pg_buffercache of
the postgres or it also takes into account the *linux buffers* that postgres
uses?
