lost data, possible playback?

[Palle Girgensohn <girgen(at)pingpong(dot)net>]

Hi!

A user accidentally deleted some results (i.e. tuples in a postgresql 
database) created this morning.

I have pg_xlog from about 9 o'clock until now. I have a pg_dump from ab out 
3 o'clock this morning.

The results where created from about nine o'clock until noon, when the user 
accidentally removed the results.

Would it be possible to replay the WAL logs and get the results from 
pg_xlog + the dump? Or from a file system snapshot as of now (five pm) + 
pg_xlog?

Regards,
Palle
