The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/app-pgdump.html Description:
To dump a database into a custom-format archive file: $ pg_dump -Fc mydb > db.dump There should be a warning here stating that (or similar): Windows Powershell alters binary data on redirect, and hence corrupt the archive. For Windows Powershell, the -f option should be used.
