Hello,
May I know how to generate drop table cascade when pg_dump a schema please?
E.g.,
pg_dump -h db_server -E UTF8 -n schema_name -U schema_owner --clean
-d db_name >! ~/a.dmp
In a.dmp, I'd like to get:
drop table t1 cascade;
drop table t2 cascade;
... ...
Only dropping constraints within a schema is not good enough since there
are dependencies on other schema.
That is a limitation of dumping by schema.
http://www.postgresql.org/docs/9.2/interactive/app-pgdump.html
"Note: When -n is specified, pg_dump makes no attempt to dump any other
database objects that the selected schema(s) might depend upon.
Therefore, there is no guarantee that the results of a specific-schema
dump can be successfully restored by themselves into a clean database.
If you want to reach across schemas you either need to do a whole
database dump or modify a partial dump or create your own script.
Thanks a lot!
Emi
