postgresql-common 74 (amd64 binary) in ubuntu gutsy

 postgresql-common provides a structure under which multiple versions of
 PostgreSQL may be installed and/or multiple clusters maintained at one
 time.

 If you have openssl installed, this package will automatically create a (self
 signed) SSL certificate so that SSL works out of the box.

 PostgreSQL is a fully featured object-relational database management
 system. It supports a large part of the SQL standard and is designed
 to be extensible by users in many aspects. Some of the features are:
 ACID transactions, foreign keys, views, sequences, subqueries,
 triggers, user-defined types and functions, outer joins, multiversion
 concurrency control. Graphical user interfaces and bindings for many
 programming languages are available as well.
