oh yeah lall postgres update:* successfully backed up and migrated to postgres 13 * tried dumping, segfault* tried dropping indexes and dumping, changed dump format to standard SQL. postgres no longer segfaults but hits a given row and gives up when the jsonb is corrupted* thinking of writing a program that iterates by ctid and skips errors* also maybe could try finding the ctid of the rows it freaks out on and delete them
