I have one additional proposal.

I currently use this interface and have noticed that the parameter 
`option_name` in the RegisterExtensionExplainOption routine is 
case-sensitive. Since SQL treats our extended options as 
case-insensitive, it would be beneficial to either add a comment 
clarifying this behavior or forcedly convert incoming text constant to 
lowercase.
