Backup format .backup

How can i back up my database in the format of .backup
Not plain or custom or tar
Because when i restore it to PostgreSql it fails
Is it available?

Hello Hassan_Khaled_Bosha,

Could you please provide us with a link to the specification or documentation of the format you are referring to? Alternatively, are you requesting an extension so that the file has a .backup format?

Please let us know if you have any other questions.

Thank you, and we apologize for any inconvenience.
