\r (replication primary)

\r

This should not be executed manually otherwise it can disrupt replication. It is executed automatically by the replicating process on the primary process, and returns the log file name and log file count.

-r command-line option

\r (rename)

Rename file src to dst.

It is equivalent to the Unix mv command, or the windows move command (except that it will not rename to a different disk drive).
