irecovery.exe System Error: The Program Can’t Start Because libusb0.dll Is Missing From Your Computer

The irecovery.exe application is used to communicate with iPhone or iPod Touch devices that are stuck in DFU mode or recovery mode. One thing that needs to be installed for the iRecovery application to work properly is LibUSB-Win32 which can be downloaded and installed for free. The error noted below will be resolved when LibUSB-Win32 has been installed properly.

PostgreSQL SkyTools walmgr: Can’t boot Slave: DEBUG Only single loop requested, exiting

I ran into a silly error tonight during some configuration changes for PostgreSQL that took me awhile to figure out so I wanted to share so it might save others some time in the future. In an attempt to boot the slave server in a PostgreSQL SkyTools walmgr configuration I was unable to get it operational. The server would seem like it was stopping recovery mode however I was unable to login and the recovery process was still showing. Eventually I used the verbose switch to see if I could gain more information about why it was not booting up and the output is below.

Command:
walmgr.py conf/wal-slave.ini boot -v

Error:
