No, I just did "make 2>&1 | grep 'warning: conversion' | wc".
I did look through the warnings a little bit. A lot of them seem to be
caused by our being cavalier about using "int" parameters and/or loop
variables to represent attribute numbers; as soon as you pass one of those
to an API that's declared AttrNumber, warning. Another large batch are
from conversions from size_t to int, a practice that's perfectly safe for
palloc'd values. And I saw some in the planner from conversions of
rowcounts to double --- yes, I know that's imprecise, thank you very much.
Based on what I saw, there are hardly any places where a single touch
would remove a large number of these warnings; it'd be more like fixing
them retail, and it would be pretty pointless.
