The "partialclone" extension config records a string, and hence it is an
error to have an implicit bool like:
[extensions]
partialclone
in your config. We should recognize and reject this, rather than
segfaulting (which is the current behavior). Note that it's OK to use
config_error_nonbool() here, even though the return value is an enum. We
explicitly document EXTENSION_ERROR as -1 for compatibility with
error(), etc.
This is the only extension value that has this problem. Most of the
others are bools that interpret this value naturally. The exception is
extensions.objectformat, which does correctly check for NULL.
