When I look at a log with xlogdump -s /tmp/NAMEOFWAL, I always get
this at the end :
Unable to read continuation page?
BTW, the statements look like this :
0/15FFE470: prv 0/15FFE440; xid 2332; HEAP info 10 len 18 tot_len 46
DELETE FROM 16612 WHERE ...delete: ts 1663 db 16384 rel 16612 block
1413 off 5
(this is for a DELETE FROM table without any WHERE clause). I see
the XID, but can you also display date and time in the ouput ?
