Hmm. I have to say that this seems like quite the wrong way to go.
If everyplace in the system that could be calling a collation-sensitive
function has to be modified like this, we'll be fighting bugs of
omission till h*ll freezes over. Why aren't we just setting
finfo.fn_collation to DEFAULT_COLLATION_OID by default, or maybe better
letting places that inspect it take zero as meaning default collation?
Call sites should only need to call fmgr_info_collation() if they have
an explicit non-default collation to pass in.
