Good idea.  Yes, it seems to be that simple.  Here's a version like
that.  Here's an example of how it looks in pg_hba.conf:

host   all             all  127.0.0.1/32        ldap
ldapurl="ldap://localhost/ou=people1,dc=my-domain,dc=com??sub?(cn=%25u)"

Maybe we could choose a better token than %u for user name, since it
has to be escaped when included in a URL like that, but on the other
hand there seems to be wide precedent for %u in other software.
