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?
