Het bronpakket postgresql downloaden:
This is a transitional package to automatically migrate to the new multicluster/multiversion structure provided by postgresql-common and postgresql-<version>. On installation it will integrate the existing database into this new structure. You can safely remove this package afterwards.
The various procedural languages (PL/Python, PL/Tcl, PL/Perl) have now been split out to separate packages. If you use any of these languages, you need to install these packages as well.
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.
