Обсуждение: Copy Schema
Is there a way to create a "template" schema, similar to modifying the template1 to use for new database creation?
I'm trying to get consistent tables and all other metadata set in one schema and then use that schema as a template for creating other schemas in the same database as needed.
I read that there is a way to restore a schema with pg_restore command. Is the best or only way to accomplish this?
Thank you,
Derrick Betts

Any database can be used as a template. template1 is used by default. Check out the CREATE DATABASE docs: http://www.postgresql.org/docs/current/interactive/sql- createdatabase.html > I read that there is a way to restore a schema with pg_restore > command.

Well, if you haven't loaded data into a database you want to use as a template (or it only has data you want to include in the new database), you can use CREATE DATABASE as well. Hope this helps.

I know how to create new databases by using the template1 already. I want to create new schemas with the requirements outlined in the original email. Any thoughts?

If the former then check out the docs at: http://www.postgresql.org/docs/current/interactive/sql-createdatabase.html and try something like CREATE DATABASE mydb WITH TEMPLATE = mytemplatedb; If the latter then check out the docs at: http://www.postgresql.org/docs/8.1/interactive/app-pgdump.html and try something like pg_dump --file=outfile.sql --format=p --schema=myschema --schema-only --verbose mytemplatedb to generate the schema commands and psql to run them in the target database.

Thank you for your response.
This one: "add a predefined schema to an existing database."
I'll take a closer look at the document and information you provided.
Thanks again,
Derrick
