Does seem pretty inconsistent, doesn't it?
The original idea may have been to provide a substitute for a USAGE
ACL check on conversions, in which case it's not totally insane: if
you make a conversion default then you're implicitly granting it to
public. But there's no documentation about this.
Offhand I see no really good reason to have a usage check on
conversions, and would be happy with removing this one. The function
permission check at CREATE CONVERSION time ought to be sufficient.
