Mikko Partio napsal(a): Should I try remove one of the duplicate rows from pg_class?
Try before:
select oid, ctid, xmin, xmax, cmin, cmax, relname from pg_class where oid = 294397;
If both row are identical or not.
# select oid, ctid, xmin, xmax, cmin, cmax, relname from pg_class where oid = 294397;
oid | ctid | xmin | xmax | cmin | cmax | relname
--------+-----------+------------+------------+------+------+--------------
294397 | (1125,36) | 3944654557 | 0 | 35 | 35 | abc
294397 | (1124,55) | 3943984380 | 3943984642 | 3 | 3 | abc
(2 rows)
Which one should I remove? What is the worst case scenario for the delete? The database is 1,5TB so I would rather not restore it from backups :-)
