Use of 'cp -r' in CREATE DATABASE

Our dbcommands.c has for create database:
   snprintf(buf, sizeof(buf), "cp -r '%s' '%s'", src_loc, target_dir);

but my BSD/OS manual only documents 'cp -R' and mentions:
    Historic versions of the cp utility had a -r option.  This implementation    supports that option, however, its use
isstrongly discouraged, as it    does not correctly copy special files, symbolic links or fifo's.
 

I think we should switch to -R in our code.
