Export PostgreSQL Database Using Command Line

Postgres Export Database Command Line

Using pg_dump for Exporting a Single Database

To export a PostgreSQL database, utilize the command line tool pg_dump. Access the command line where your database resides. For remote databases, SSH into your hosting account. With direct computer access, open your terminal or DOS window. Run pg_dump -U dbusername dbname > dbexport.pgsql, replacing 'dbusername' with your username and 'dbname' with your database name. Ensure you have the necessary permissions.

Specifying Output Formats with pg_dump

The pg_dump tool offers multiple formats for database export. Use the -F option with pg_dump to set the desired format: plain text, custom, directory, or tar. For example, pg_dump -F c -U dbusername dbname > dbexport.dump creates a custom format file. To compress the output, pipe the dump to gzip, as in pg_dump dbname | gzip > dbexport.pgsql.gz.

Exporting All Databases with pg_dumpall

When needing to export all databases, pg_dumpall is the required command. This will create a single file containing all databases on the PostgreSQL installation.

Restoring Databases

For importing databases, use the pg_restore command if the data was exported in a format other than plain text. For plain text exports, use the psql program. Always prefer importing data as the primary PostgreSQL user to avoid issues with data access post-import.

Alternative Methods and Tools

Besides the command line, phpPgAdmin provides a graphical interface for database export. This can be an alternative for those preferring not to use command line tools.
