My patch used fsync_fname_ext() which would cause an ERROR rather than a PANIC when failing to fsync the logical decoding pathname. > Are you actually proposing that we don't PANIC after an fsync for the category > of files that you list here, even with data_sync_retry set? Yes, but I'm referring only to my change to SnapBuildSerialize(). The rest of the verbage was me trying to figure out the history/evolution of pg_fsync usage. -- Justin
