Yes !
We are looking for something providing a functionnality similar to Oracle's :-)
Through PITR or a tool or extension around wals.
Still, as wals are containing enough info for replication to work,
It should be possible to extract from wals a list of objects that have been written, and elements about what was written.
OS files written and position should be enough to provide this.
Something ?

I think he wants to see data from different tables at different timestamp (like flashback query in Oracle). As per my understanding question here is can PITR be done for specific table and for specific timestamp.

Sure, you can do that.
The description of what you wanted to do was rather unclear, all I could
make out is that you want to query AS OF TIMESTAMP.
