You're misunderstanding what identmap does.  That line says that OS user
"jorge" is *allowed* to connect as database user "gis".  It doesn't
magically substitute that username, though, and psql doesn't know any
better than to send "jorge" as the database username.  You could do
"psql -U gis", or set PGUSER in your environment.
