Hi Harish,
                      You can use EXCEPT operator for this purpose, i.e (select * from source_table except select * from target_table;) and vice versa. Thanks.

Hi 

You can also use pgAdmin for schema comparison, please check the below link.

Dear Harish,
If you are referring to data validation then the following query might give you the desired results

/pg_dump -U postgres -s target -p 5334 > /tmp/db2_schema.sql ./pg_dump -U postgres -s source > /tmp/db1_schema.sql diff /tmp/db1_schema.sql /tmp/db2_schema.sql

Adjust your ports and databases name accordingly

Dear Admins

Is there any way to do data comparison for the database scheme in PostgreSQL between old version(10) and new version (15.0).

Just migrated database from version 10 to 15.

Much appreciate your help.

Regards,

Hari
