I already do something similar: the wrapper fails if the
target db exists before a restore is even attempted. The
restore itself now uses --create and works as expected. The
only thing left ATM is that I cannot distinguish
success-with-or-without-ignored-errors from real failure.
I _can_ partly work around that by attempting to connect to
the target and checking the md5 sum of the schema definition
against a known hash. That won't help with detecting whether
pg_restore thought that _data_ was successfully restored ...
I'd operate under the premise that all warnings and errors are fatal (i.e., keep --exit-on-error) until you cannot for some very specific reason. I'd decide how to proceed at that point. For instance pg_restore does provide an ignored error count at the end - you could scan the log for expected errors, count them, and compare to that value and fail if the count differs.
But this particular warning should be easy to work around and you shouldn't expect any others that would be considered non-critical.
