The reason this doesn't work is that SPI can only be invoked inside a
transaction, and you're not inside one when a library is being
preloaded.

You could maybe make this work by executing your own transaction
to do it, but I really have to wonder if it's a good idea. One
point to think about is that elog(ERROR) still means elog(FATAL)
at this point, so any brokenness in the queries you're trying to
prepare will result in locking all users out of the database.
