I've got binary operators working with automated type conversion, at
least for some cases:
tgl=> select 2.0 > 1;
?column?
--------
t
(1 row)
However, I'll need to revisit the search algorithms for matching
possible types to functions and operators; I'm pretty sure that the best
algorithm (or even the minimally acceptable one) isn't in there yet.
On to target type matching...
