Subject: [PATCH] libpq: Fix incorrect message type in getBackendKeyData()
 comment

The getBackendKeyData function comment incorrectly stated that the
BackendKeyData message type is 'v', when in fact it is 'K' as defined
in protocol.h. This fix corrects the comment to match the actual
message type used in the protocol.
