This plugin implements a user-friendly interface for the PostgreSQL backup tools pg_dump, pg_dumpall, pg_restore, and psql. This extra feature was developed mainly focused on attending to those users less comfortable with command-line tools, being possible to dump and restore databases without leaving pgModeler's GUI.
In a nutshell, besides configuring the backup tools parameters with a simple form, it allows the creation of presets per backup tool for different needs, it also has some facilities that automate the backup file name generation by using a default backup folder and name patterns. Since the plugin reuses the configured connections information passing them to each backup utility command, make sure to use credentials that can log in to the server and perform a dump or restore or the mentioned processes will fail.
The image below shows the pg_dump section of the plugin. The options there are user-friendly labels for each command-line option of pg_dump command, in case of doubts, you can always refer to the official PostgreSQL docs to obtain detailed information about them. Specifically for Dump and Dump all sections, selecting a connection and a database name in the
Databasegroup at the top-left portion of the form, will trigger the automatic output filename generation according to the parameters defined in the Settings tab. If none of the automatic name generation parameters is defined, then you have to manually specify the output filename.
The backup plugin settings section is quite simple and demands almost no user interaction in a normal initialization. In the
Backup utilities paths, the plugin tries to locate the needed PostgreSQL backup utilities and assign them to each selector. If one or more executables couldn't be found the related selector will display a warning sign so the user can fix the problem. In the
File name patterns, is where the automatic name generation feature is configured. The first two fields,
pg_dumpall are the name patterns used in Dump and Dump all sections. In those two fields, hitting
Ctrl+Space shows a popup with the available tokens used by the patterns to create the output file names. The
Default folder selector is a valid path to a folder where all the backups will be saved. Finally, the
Automatic names generation option toggles the whole process of generating a name based upon the options configured in the group, while the option
Disambiguate conflicting names will avoid the generation of names that somehow may overwrite a backup file already preset in the output folder.
Once you have tweaked all the desired options in the backup utility tab, just hit Run to start the selected backup tool. Once started the process, all the output will be displayed in the Output tab like the image below.
