用于开发生产环境的Postgres数据库设置

Question

I'm deploying an App using PHP (CodeIgniter framework) and postgres (i'll probably use some javascript on the client side).

I'm using a Git repository with the dev-staging-production branches, and I'd like to know what is the best way to implement the databases with postgres.

Should I create three tables for each with a prefix ie dev_, sta_, prod_? should I synchronize some tables, and how should i sync them...

Answer 1

Instead of multiple tables I'd either go with a) multiple schemas or b) multiple databases. The latter option is preferrable since this allows you to run dev and staging databases on other hosts than the productions database.

In principle you would then manage your data in the production database only and sync them to the staging and dev database regularly or on demand, eg with pg_dump and pg_restore .

halfer 's comment on managing schema changes is a good approach.
