Restore a full data dump for MySQL and PostgreSQL
You can restore data dumps by using the mysql client utility for MySQL, or pg_restore or psql for PostgreSQL. The pg_restore option is used for custom-format pg_dump -Fc or directory-format pg_dump -Fd dumps. The psql option is used for SQL-format dumps.
If you see no restore options in the context menu, verify that you use a correct JDBC URL for the data source.
In the Database tool window ( ) , right-click a schema or a database and navigate to the Import/Export group:
Restore with "mysql": for MySQL data sources. In the Path to mysql field, specify the path to the MySQL executable (for example, C:\Soft\mysql-8.0.19-winx64\bin\mysql.exe).
Restore with "pg_restore": for PostgreSQL data sources. The pg_restore option is available for the most database objects except for the data source level.
Restore with "psql": for PostgreSQL data sources. The psql option is available for the most database objects except for table and schema levels.
Restore: for PostgreSQL data sources. Includes two tabs: pg_restore and psql.
In the Restore with <dump_tool> dialog, specify the path to the restore tool executable in the Path to <dump_tool> field.

In the settings pane in the upper-right part of the dialog, configure mapping settings and change settings of the sources (CSV file, table, and query). The preview pane in the bottom part of the dialog displays generated previews of your data, of the source data with different source settings, and of DDL statements.
