postgres.org doesn't work

We own the domain name postgres.org, but it doesn't pull up our web
site:
$ host postgres.orgpostgres.org has address 66.98.251.159postgres.org mail is handled (pri=0) by
mail.postgres.orgpostgres.orgmail is handled (pri=5) by mx1.hub.orgpostgres.org mail is handled (pri=5) by
mx2.hub.orgpostgres.orgmail is handled (pri=10) by mx3.hub.org
 

Same for postgres.com:
$ host postgres.compostgres.com has address 66.98.251.159postgres.com mail is handled (pri=5) by
mx2.hub.orgpostgres.commail is handled (pri=5) by mx1.hub.orgpostgres.com mail is handled (pri=0) by
mail.postgres.compostgres.commail is handled (pri=10) by mx3.hub.org
 

For comparison is of course works:
$ host postgresql.orgpostgresql.org has address 200.46.204.71postgresql.org mail is handled (pri=10) by
mx2.hub.orgpostgresql.orgmail is handled (pri=10) by mx3.hub.orgpostgresql.org mail is handled (pri=0) by
mail.postgresql.orgpostgresql.orgmail is handled (pri=10) by mx1.hub.org
 

What other domains do we own and do they all work?
