Thanks. Is it by doing these steps I can avoid constrain restriction? for step 3, how should I modify the schema? and which schema? the target DB's schema that I am trying to dump the schema and data in? But this is the problem, I am not sure whats different between the two schema's, there are just too many tables to check. What's your tips?

Using pg_dump from your new host (that is, newer version)
1- Dump schema.
pg_dump -h server_source -U username -s -Fp -f schema.sql database
2- Dump data only.
pg_dump -h server_source -U username -a -Fc -f data.dmp database
3- Modify schema.
4- Restore schema in new host.
psql -U username -d database -h server_destination -f modified_schema.sql
5- Restore data disabling triggers
pg_restore -h server_destination -U username -d database --disable-triggers -a data.dmp

Hi all,
I am dumping both schema and data from old database to new one. The new database schema is somehow contain slightly different schema then the old one. When I do restore it shown alot errors related with constraints. How can I dump and to restore from old to new without dealing with constraint and just forces data dump to where it suppose to belong?
