Hello,
I'm looking forward to the doc update.
My 0.02€ about prompting:

I like the "tfz" idea. I'm not sure whether the up to 6 characters is a
good, though.

Hmmm. Logically I would say prepend, but the default prompt is with the
dbname, which is mostly letters, so it means adding a separator as well.

I would say yes.

Yep, but with a separator?

Hmmm, not sure...
Based on the your ideas above, I would suggest the following:
calvin=> \if true calvin?t=> SELECT 1 + calvin?t-> 2; 3 calvin?t=> \if true calvin?t=> \echo hello
hello calvin?t=> \endif calvin?t=> \else calvin?z=> \echo ignored calvin?t=> \endif calvin=>
Or maybe use "?.t" for the nested if...
