Just checked and both worked fine. Did 30000 transactions per 10 concurrent clients with pgbench and the pg_xlog/
foldernever went beyond the initial size (files were rotated inside pg_xlog/, none archived, no errors in the
PostgreSQLlog). 

I think I'll stick with the "exit 0" one, as the cp would have to read the file (although it would probably be in the
cacheof the kernel as it was just written?). 

Now on how to change the archive_command in runtime without having to modify the postgresql.conf file, if possible...
:P
