The error message: pg_dump: warning: WITH OIDS is not supported anymore

Hello! I use SQLBackupAndFTP to backup three PostgreSQL databases, but I get a message while backup first database:

06.04.2021 22:07:52 [Error] Failed to backup “upp” database with “Full” backup type: C:\Program Files (x86)\SQLBackupAndFTP\DBMS\PostgreSql\pg_dump.exe process has finished with “1” code. The error message: “pg_dump: warning: WITH OIDS is not supported anymore (table “_yearoffset”)

What does this error mean? How can I fix it?
