I didn't run to do anything ;) I had a good think and a good google
before I done anything and I have all my data back because of it.
Luckily for me the data was neither life or job threatening so I was
able to take a few more risks than necessary. I was actually
volunteering to write the database recovery section of the docs, not
asking for help.
As per TID wraparound. I have been lucky enough never to have received
anything similar to the following warning (taken from 7.4 docs)
play=# vacuum;
WARNING: Some databases have not been vacuumed in 1613770184
transactions.
Better vacuum them within 533713463 transactions,
or you may have a wraparound failure.
VACUUM
you will also notice that I used a TID of less than 100 million to
recover the database. I was nowhere near 0.5 billion as recommended by
the docs.
