What is a PGERD file?

PGERD files mostly belong to pgAdmin4. PGERD files are used by pgAdmin4 to store entity relationship diagrams for PostgreSQL databases. They contain database design information in JSON format, which means the file is plain text structured data.
Inside a PGERD file you will find details such as:

Entities: Definitions of tables and columns.

Relationships: Links between different tables.

Layout Settings: Coordinates and display options for the diagram.

FilExt.com note: This file format allows the ER diagram to be easily read by both the pgAdmin4 tool and any text editor. For further technical details and support, refer to the pgAdmin website.

How to open a PGERD file

You need a suitable software like pgAdmin4 to open a PGERD file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PGERD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PGERD file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert PGERD files:

pgAdmin4
See the previous paragraphs to learn more about the main application. PGERD files are often referred to as pgAdmin4 databases because this type of file is primarily created or used by this software.
pgAdmin4
A .PGERD file stores a PostgreSQL Entity Relationship Diagram (ERD) in JSON format. It is created by pgAdmin4, a popular PostgreSQL administration and development platform. The diagram visually represents the database structure, including tables, columns, relationships, and constraints. This allows developers and database administrators to design, analyze, and document the database schema effectively. This file format is classified as Database.

PGERD file format:

The file format determines how the data is stored in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the PGERD files looks like this:

PGERD is a very widely used file extension. The file type is mainly used by one program with a specific format. The two most popular formats are as follows:

99% of all PGERD files are based on the well-known JSON file format. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. If you open these files in a text editor, you can view and read the content yourself. The file size is in the range of 42 KB to 1 MB. The file type is a fairly new file format. Several words can almost always be found in the files, e.g. data, gridSize, layers, offsetX, offsetY, version and zoom. Some examples of file names are ERD.pgerd. Files like these are about schema, diagram, diagrama, database, modelo, model, data and entidad.

All other PGERD files (1%) have no uniform format. These files are often connected to project, base, prod, relacion, current or relacional. You can get all the details of your PGERD file by dragging it onto this page or by clicking the button "Choose your .pgerd file to view" above.
