[Bug] apache cloudberry gpbackup 2.1.0

Comienza reproduciendo gpbackup 2.1.0 contra una base de datos Apache Cloudberry 2.0 con un paralelismo de 3 y una compresión de 2. Rastrea el fallo reportado desde backup/wrappers.go:187, pasando por backup/backup.go:51 y gpbackup.go:31. La finalización debe demostrarse mediante backups a nivel de esquema que ya no produzcan el error de bloqueo seguido de la advertencia de limpieza de un puntero nulo.

Apache Cloudberry version

I am getting the below error when trying to take schema level backups from a apache cloudberry 2.0 database and I am taking one schema after the other using gpbackup 2.1.0 utility from a bash script. Also I am using parallelism as 3

Note: I recently build the apache cloudberry 2.1.0 gpbackup utility from the source code --> https://cloudberry.apache.org/releases/#releases
