Hi Vince,
For validation of databases, you can use the following approach

/usr/pgsql-16/bin/pg_dump -d postgres -h localhost -p 5428 | md5sum >
/var/lib/pgsql/db1.txt
/usr/pgsql-16/bin/pg_dump -d postgres -h localhost -p 5420 | md5sum >
/var/lib/pgsql/db2.txt
diff db1.txt db2.txt

By executing above queries, if diff is null then it means there is no
difference between source and destination databases. Adjust your port and
databases accordingly.
