Thank you all for your responses. I'm aware of xlogdump but I'm afraid it does not help me with readign the data in the WAL. It is mainly "for debugging or educational
purposes" (citing the docs) and it outputs a lot of information about the WAL records but not the contents of them (e.g. it says where an INSERT wrote the data, but not what the data is). Please correct me if I'm mistaken.
What I'm looking for is a way to read the data that is inserted into the database. I was hoping there was some known way of doing that to save me the time it takes to patch Postgres to do that.
Regards,
Baldur

It only became available with Postgres 9.3. On prior versions, you can use:
