I would apply this argument to every single part of the system that requires code that extends the database to be
writtenin C, including:
* I/O functions (for custom data types)
* tsearch parsers
* use of RECORD arguments
And probably many others. There are a *lot* of problems I’d love to be able to solve with prototypes written in PLs
otherthan C, and in small databases (there are a lot of them out there), they may remain the production solutions.
So I buy the argument in the case of creating range canonicalization functions, too, of course!
