Yet another metric used to define an initial release is the date of the 1.0 version.
From the first archive capture [1] this is "Postgres95 1.0 ... Tue Sep 5 11:24:11 PDT 1995"
That is the Postgres95 version 1.0. There was also sometime in ancient history a Postgres 1.0 I believe (though I don't think it ever made it outside Berkeley?)
So it depends on if we're doing the birthday for Postgres, Postgres95 or PostgreSQL.
