Regarding database backup during up gradation of website

Hello All,

We are developing one website and creating some tables as part our customised module development.I have observed many tables get created as part of our drupal installation.  Now I wanted to replace the newly developed website(druapl 7) with the old website(druapl 7). 

I wanted to take the backup of old site then I will replace the new website. I have taken database  backup of customised module and “user” & “user_roles” from default tables. 

Could you please suggest me what are other default tables needs to be taken backup before replacing the new website ?

Note : I am using Postgresql .

Regards,
