hmmm...not sure I know what you mean.

It is very-very-close-to-impossible to edit the transaction logs
manually, unless some form of special-format editor were written for the
purpose.

Is it clear that the PITR features are completely different from
pg_dump? (Which would allow a manual edit and recover). The xlogs are
binary files that refer to all changes to all tables in a cluster
ordered by time, rather than by table.
What I meant by hand-restore was

1. A total backup occurrs on Monday morning

2. Transactions occur on Monday, Tuesday and Wednesday, with PITR
archiving enabled

3. Intern deletes everyting from obscure_table on Thursday afternoon
and wants to restore it as it was on Thursday morning

4. On some other machine, the total backup is restored into a new
cluster, the transaction logs replayed to that point-in-time where
intern deleted everything from obscure_table

5. The table is dumped manually and restored in the production
database, because it is known that this table has no logicial
implications for the consisetency of other tables.

That's what I meant by hand-restore.
Excellent. Thanks very much for the clarification. I was worried that I
had misrepresented the functionality, but you have it spot on.

The scenario you describe is going to be possible now...

Best Regards, Simon Riggs
