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 is strongly discouraged, as it
     does not correctly copy special files, symbolic links or fifo's.

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