No. pg_dump output and WAL files are at two utterly different levels of abstraction --- the WAL files describe the exact placement of tuples within tables and indexes, to mention just one example. There's no hope of using pg_dump output to reproduce the state of a database exactly enough that you could apply WAL files to it. regards, tom lane
