PostgreSQL

PostgreSQL

PostgreSQL is a very capable open-source object-relational database system. It evolved from the Ingres project at the Berkeley University.

Leader of the Ingres team was Michael Stonebreaker. In 1985 he started a new project, called POSTGRES for post-ingres, which had ability to define types and fully describe relationships. It could fetch data in related tables using rules, a novel concept. First version was released to small number of users in 1989. In 1996, with initial support for POSTQUEL language replaced with SQL, POSTGRES changed name to PostgreSQL to reflect its support for SQL. Since 1997, a group of developers and volunteers around the world maintain the software as The PostgreSQL Global Development Group.

PostgreSQL is extremely feature-rich, comparable to proprietary enterprise databases like Oracle, SQL Server and DB2. PostgreSQL uses multi-version concurrency control (MVCC) to avoid locking and has a rich programming support in form of PL/pgSQL (equivalent to Oracle’s PL/SQL). It can even use external programming languages through extensions (currently supports Perl, Python and Tcl, with more to come). Recently performant JSONB datatype was added, making PostgreSQL a viable competitor to document/store databases such as MongoDB.

Many companies use PostgreSQL as a base for their proprietary enhances database projects.

PostgreSQL is continuously maintained for almost 30 years. It’s a completely free database with top-notch capabilities and reliability. We warmly recommend it as a production database and use it ourselves.

Full Convert supports PostgreSQL database directly. PostgreSQL is also known as Postgres, PG

Export PostgreSQL database

It may make sense to migrate your data away from PostgreSQL. You may want to do it permanently or just need to share your tables with a collague in a different format.

We will copy all your tables with their data and apply indexing and relationships exactly as they are in your current PostgreSQL database. In a nutshell, you get exactly the same database in another database engine. Each time you run the migration, we will copy all the tables again. Of course, we have a built-in scheduler, so you can run this overnight and have a fresh database copy in the morning.

Take a look at the quick tutorials below to see how it's done.

Import data into PostgreSQL database

Additionally, if you want to import data on a regular basis and do not want to recreate the whole target database from scratch every time, but rather do tiny targeted sync of only changes since the last run, please use Full Convert Pro or Ultimate.
