+1 for (1) personally, if we could think it is not in English but just
a symbol. I have another idea to make it alike with ANALYZE output.

(4) Blocks (shared hit=2 read=1641 ...) (local hit=0 ...) (temp read=0 ...)

Which is the best? I think it's a matter of preference.
(0) 109 characters - Shared Blocks: hit 2 read 1641 wrote 0, ...
(1) 105 characters - Blocks Shared: (hit=2 ...
(2) 96 characters - Blocks Shared:hit=2 ...
(3) 82 characters - Blocks Shared:(hit=2 ...
(4) 82 characters - Blocks (shared hit=2 ...

BTW, I found text is a *bad* format because it requires much discussion ;)
We have a little choice in XML, JSON and YAML formats.
