Hi,
I can only think, You could try to parse page files. If you didn't do VACCUM
FULL you could try to restore it, if those rows was not overwritten after
VACCUM (normal). Maybe some "internal" guys can give you answer (if e.g.
VACCUM (nomral) zeros row).
The programm to restore will bo so tricky as file system undelete, and it will
have same requirements as.
Here I found some link (I gooled "postgresql find deleted tuples"):
http://postgresql.1045698.n5.nabble.com/Restore-deleted-rows-td2005963.html
I think I saw quite interesting idea of "trash" for vaccumed tuples.
Kind regards,
Radosław Smogura
