Re[2]: Getting error while upgrading postgres from version 12 to 13

Hello,

As per error it seems you have initiated source data with PG13 binaries. 

Could you please connect to both source and target psql and share out of select versions();

Also share pg_upgrade complete command which you are using. 

Regards,
Abdul Sayeed
