Thread: WAL file creation
Does anybody know if it is possible to create a set of *blank* WAL files for PostgreSQL 8.1, knowing that the database was safely shut down and all data is in tact?
The reason is that during the weekend I failed our master database over to our disaster recovery site, put that in read only mode, whilst I upgraded the master database, and after completing the upgrade and shutting the master down, I some how messed up re-connecting DRDB and lost all the new WAL files. From that point on the master would not start-up for obvious reasons, but I knew there were no pending transactions to be rolled forward in the WAL files, yet without a valid WAL file its impossible to start PostgreSQL.
Thanks in advance,
regards
