Problem Statement:-

How to backup and restore a PostgreSQL database without column names mismatch.

The database is the heart of an application. It is a strategy used to store, update, and delete data on the server. Although it stores data, it does not include end-user application elements such as stored queries, forms, macros, or reports. Users can indirectly access the database through an external application. A few of the databases used to develop software are SQL, Django, MS Access, etc.

Description of the Issue:-

I was working on a project that forced me to use the same database on a different server. Thus, I had to create a backup of that database to restore it in the new server. Initially, I made the backup of each table using the export and import feature. However, I found that columns of newly created table properties were different from the old tables. I could not find a solution, although I researched many technically sound websites. Later, I tried to create a backup by changing backup properties. I finally succeeded in the process of backing up and restoring a PostgreSQL database without losing data.

The Solution Offered:-

Here are a few steps that have to be followed to get the desired solution.

a. Create an empty database in the server where you want to restore.

b. Create a folder for you to store the backup file.

h. Now, click on start

Now, click on start

i. Now, the dumping process will start. After completing the dump, a popup window opens, and click on OK to complete the backup successfully.

Steps for restoring database:-

a. Select the database in the required server and right-click on that to select tools, and then select the restore option.

Select the database in the required server

b. Now, the restore settings window will open, select format as custom and choose the backup file from the folder you created for back up, select SQL files, and finally select the backup file inside that folder.

Now, the restore settings window will open

c. Now, check all checkboxes, add the client as PostgreSQL binaries, and click OK.

add the client as PostgreSQL binaries

d. Click on start, and the database will start restoring. After the restoring process is done, a PostgreSQL popup window will open, click on ok to complete the process successfully.
