I agree that this is useful information to have, but why add it to
\dAo+ instead of \do+? Taking the example from the original thread,
when writing a query containing 'tsvector @@ tsquery', it's much more
obvious to use "\do+ @@" to check if it's leakproof, rather than
"\dAo+ gin".
Perhaps it would be useful to have this in \df+ output as well.
I notice that this patch spells "leakproof" with a hyphen. IMO
leakproof should not have a hyphen -- at least, that's how I naturally
spell it, and I think that's more common, and it matches the SQL
syntax.
We haven't been consistent about that in the docs and code comments so
far though, so I think we should make a decision, and then standardise
on whatever people decide.
