The check_oauth_validator check for an empty validator list didn't test for a string with only whitespace, which would cause the postmaster to crash. Instead of testing for the empty string cases, pass the config value to SplitDirectoriesString unconditionally. If an empty list is returned then the input string was empty. Since pstrdup cannot handle NULL, assert that the string ie set. While users cannot set the string to NULL, it is initialized to NULL so guard against programmer error. Check the parsed list instead. Assert that the GUC string is non-NULL before pstrdup(); users cannot set it to NULL, but the C variable is initialized that way. This also adds a TAP test that reloads a whitespace-only setting after pg_hba_file_rules and waits until the existing backend sees the restored GUC.
