Ugh. I think I have seen that happen too --- if the CREATE CONVERSION
commands fail during initdb, initdb doesn't notice or tell you about it.
It would be a good idea to fix that. Perhaps the standalone backend
could be extended with a command that tells it to exit with nonzero
status if it gets any error?
