Then another pg_clog file disappeared.

OK, I have:

bookstor=# SELECT * FROM core_wot_seq;
   sequence_name   | last_value | increment_by |      max_value      | 
min_value | cache_value | log_cnt | is_cycled | is_called
------------------+------------+--------------+---------------------+-----------+-------------+---------+-----------+-----------
  core_wot_seq     |       2593 |            1 | 9223372036854775807 |         
1 |           1 |       8 | f         | t
(1 row)

bookstor=# SELECT 1 FROM core_wot_seq;
  ?column?
----------
         1
(1 row)

bookstor=# SELECT 1 FROM core_wot_seq FOR UPDATE;
ERROR:  could not access status of transaction 1573786613
DETAIL:  Could not open file "pg_clog/05DC": No such file or directory.

How do I best recover from this? Stop postgres, create an empty, 256k 
pg_clog/05DC file, start postgres?

Export table, drop table, import table? Anything else?

Nobody has a clue? :|
