+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 -
BlocksShared:(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.
