Ah.

I've added a quote_ident() around unnest() - otherwise the
auto-completions for default_transaction_isolation will mostly be wrong
due to spaces.

I also renamed get_vartype into get_guctype, changed the comment as I
found the reference to the pg type system confusing, and more
importantly made it not return a static buffer.

The spellings for boolean values were a relatively small subset of what
the backend accepts - it's now on,off,true,false,yes,no,1,0. I'm not
sure whether that's a good idea. Comments?
