You are rehashing an argument that I already rebutted: the way to solve
this problem is with the macros, the format of which we were discussing
in this sub-thread. I am not sure why you bring it up again.
You say the reason for not exporting the struct definition is that you
can later change it without having to touch the callers. That seems a
good argument, and it seems to me to work equally for pg_amop as for the
new header KaiGai is creating here.
In any case, at the start of the thread KaiGai was asking for opinions,
and I gave mine. I will now shut up.
