Thanks for the information! That looks promising, I will attempt to
implement it this week and let you know.

Never had a need for this. One thought that comes to mind write a
plpgsql function that takes in name of new schema and old schema and
does something like below
--Create new tables in new schema
FOR tbltocopy IN(SELECT table_name
FROM information_schema.tables
WHERE table_type = 'BASE TABLE' AND
table_schema = param_source_schema ORDER BY table_name)
EXECUTE('CREATE TABLE ' || param_dest_schema || '.' || tbltocopy
|| '( LIKE ' || param_source_schema || '.' || tbltocopy || ' INCLUDING
DEFAULT CONSTRAINTS INDEXES ');
INSERT INTO ' || param_dest_schema || '.' || tbltocopy || ' SELECT *
FROM ' param_source_schema || '.' || tbltocopy || ';');
NEXT;
Hope that helps,
Regina

Subject: [NOVICE] How to copy a schema under another name in same
database
Hello! I have a PostgreSQL (8.3.3, WinXP + linux) database with
multiple
schemas. I would like, on a regular basis, to be able to copy the
structure
and data of one schema under a new schema, using of course a different
name.
What would be the easiest way?
- I have seen the TODO entry "Add CREATE SCHEMA ... LIKE that
copies
a schema", so I guess an easy solution (a single pgsql command) is not
yet
available...
- I guess the alternative is to use pg_dump to dump a single
schema
and use pg_restore, but how can I restore the dumped information under
another schema? I would like to avoid dumping it as an sql script and
having
it to modify it manually, because this will be a regular operation that
I
would like to automate in my application.
Thanks in advance for any insight you can provide!
