#' @title Restore the CDM (undo the pruning).
#'
#' @description This function undoes the pruning by renaming (the *_orig tables are given their names back).
#'
#' @param connectionDetails  An R object of type\cr\code{connectionDetails} created using the
#'                                     function \code{createConnectionDetails} in the
#'                                     \code{DatabaseConnector} package.
#' @param cdmSchema  The name of the database schema that contains the CDM
#'                                     instance.  Requires read and write permissions to this database. On SQL
#'                                     Server, this should specify both the database and the schema,
#'                                     so for example 'cdm_instance.dbo'.
#' @param cdmVersion The version of your CDM.  Currently "5.3.1" and "5.4.0" are supported.
