How to export data from a PostgreSQL database

Data export is one of the most frequently used processes when working with databases. It can be a powerful and useful tool that allows database administrators to export tables and entire databases without much effort. There are many different ways to go about exporting data in PostgreSQL. Now, let us take a closer look at some of the most popular ones.

pg_dump command to export PostgreSQL databases

pg_dump allows you to extract a PostgreSQL database into a script file or other archive file. It is used for backing up purposes. The basic syntax looks like this:

pg_dump [connection-option...] [option...] [database_name]

In this syntax, database_name specifies the name of the database to be dumped. The rest of the options control the content and format of the output. For more information about the options, feel free to turn to the official PostgreSQL documentation.

Export a PostgreSQL dump:
The easiest way

If you need to restore a PostgreSQL database from a dump, you do not necessarily have to deal with complex queries. Fortunately, there are modern tools like dbForge Studio that can shorten the Postgres dump and restore process to just a few clicks:

Click Database and select Execute Large Script.
The Execute Script Wizard opens.
Choose the corresponding connection and database.
Browse the SQL dump file that you are willing to execute.
Select the SQL file encoding from the list.
Click Execute.

Export PostgreSQL data to CSV: An example

Exporting data from PostgreSQL to .csv has never been easier. The Studio will walk you through the process and do the majority of the work for you. In order to export only a part of the PostgreSQL data to a .csv file follow these three simple steps:

Select the data that you are going to export.
Right-click the selected area.
Click Export Data.
