How would a failed transaction make any entries in such a table?  How
would you handle maintenance operations on the table that require
exclusive lock?  (vacuum full, reindex, etc)

It seems possible that you could make this work if you piped stderr to a
buffering process that was itself a database client, and issued INSERTs
to put the rows into the table, and could buffer pending data whenever
someone else had the table locked (eg for vacuum).  I'd not care to try
to get backends to do it locally.
