Обсуждение: recovery from idiot delete error

Hello...

I'm in rather dire-straits here. I just mistakenly deleted all the 
entries in a table and I need to recover them. I'm told that there's 
something I can do along the lines of "hacking up a PG to show deleted 
'tuples'" ...

Any help would be VERY much appreciated.

What version is this?  In recents ones you can change
src/backend/utils/time/tqual.c or just compile with
-DMAKE_EXPIRED_TUPLES_VISIBLE in CFLAGS
and *I think* you should be able to see deleted tuples.
