shiftcorruption is for a really specific case of corruption where extra bytes have been inserted into database files moving the rest of the file forward. xlogfilter is for when xlog replay fails with some error on some specific table or index, but you want to finish recovery on the rest of the database. trycopy is probably the most useful, it tries to copy out all of the table to a csv file, using physical tuple addresses to skip over rows that cause errors or crash the server.
