Extract text from PostgreSQL backup files (CUSTOM)
To convert CUSTOM backups to another format, you need PostgreSQL or other Database software.
To convert other file formats to the "PostgreSQL Backup Dump" file type, you need software like PostgreSQL or a similar tool.
The .custom file is a binary database backup generated by the pg_dump utility in PostgreSQL. It stores table structures, relational data, and schemas in a compressed format. It is designed for efficient backup and selective restoration of database objects.
Unlike a plain text SQL dump, a .custom file is proprietary to the PostgreSQL backup and restore system. It is a binary format that cannot be opened natively by web browsers, standard text editors, or spreadsheet software. Users frequently face problems when trying to inspect the data without having access to a running PostgreSQL server or the specific pg_restore command-line tool.
Converting .custom to standard formats like SQL, CSV, or TXT is often necessary for data analysis, auditing, or migration to other database systems such as MySQL or SQLite. Converting to CSV may result in the loss of database table relationships and schema triggers.
Because .custom is a specialized binary format, standard online converters fail to process it. Often, only the original PostgreSQL software can properly read or export the data. However, just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your CUSTOM file, detects the exact format, and lets you read the text inside.
Users also converted WEBP, PDF, HRV, SVK and THX files.
If you want to convert CUSTOM file to , you can use PostgreSQL or similar software from the "Database Backup Storage" category. In the File menu, look for Save As… or Export….
To convert files to CUSTOM, try PostgreSQL or another comparable tool in the "Database Backup Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CUSTOM converter.
