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? -- Thank You, Subham Roy, CSE IIT Bombay.
