Обсуждение: Changing schemas

    Is there a way to change the schema that all objects are in?
Essentially I want to move everything currently in the database into
public rather than having the complex schemas that I have at the moment.
They are unnecessary and the DB complexity is trivial, so using schema
partitioning is more trouble than it is worth. Is there a way I can do
this? I tried editing a dump, but that has proven to be a little
difficult, as I am not a master of regex.

If I can do it from within the DB before I do the dump that'd be easier.
Is there a way to do this from within the DB?

Thanks,
- Naz.

ALTER TABLE name
     SET SCHEMA new_schema

Try renaming the schema. alter schema schemaname rename to newname;
then if you want the old schema back create a new one.

If there are already stuff in the schema you want to move to then
write a quick function using a for loop with the pg_class table
to write the alter table statement for anything that has the
schema you are looking for.

I need a single command to change ALL objects

Something like "alter table (select name from tables where schema =
'foo') set schema bar"
