+Title: Part of Postgresql 9.0...
+Date: 2010-05-07
+Tags: technical
+Slug: part-of-postgresql-90
+
+I've
+contributed to another open source project, Postgresql. My first
+contribution [made it into version 9.0][].</span>
+
+I
+worked on the ```samenet``` and
+```samehost```
+host
+based access control feature, which lets you grant database access to
+hosts on the physical subnets that the postgresql server is attached
+to.
+
+Previously many postgresql
+deployments for clients used to have
+```0.0.0.0/0```
+in
+the
+pg_hba.conf
+file,
+because more limited access controls were too brittle and would
+inevitably fall over when the client renumbered their network.
