Greetings. I cannot get understanding about what different types of blocks means here: http://www.postgresql.org/docs/current/interactive/pgstatstatements.html
I assume, that `shared` are blocks from the `shared_buffers` and `temp` are blocks used by temporary files (absence of `dirtied` and `hit` also speaks for this). But what `local` blocks mean? -- Victor Y. Yegorov
