Is this a neat idea?

SELECT * FROM (SHOW ALL);

eg.

SELECT * FROM tab WHERE character_length(f) > (SHOW block_size);

etc.

So neat in fact that it has been implemented.

SELECT * FROM pg_settings;

Damn! I knew that as well! *sigh*

I'm not thinking right from my current 'shocking postgres performance
problems nightmare day' today :(

Think massively concurrent table that almost everything on the site
relates to causing heaps of select queries to pile up and use all I/O,
getting worse, etc...
