将 Heroku PostgreSQL 转储导入本地数据库时遇到问题

Question

我正在尝试将 PostgreSQL 转储从 heroku 导入本地数据库（以模拟本地环境中的生产数据）。我正在 OSX 上本地使用 postgres 9.2。以下是我在控制台中采取的步骤：

dropdb db_dev

createdb db_dev

heroku pgbackups:capture HEROKU_POSTGRESQL_MAROON_URL

curl -o latest.dump `heroku pgbackups:url`

pg_restore --verbose --clean --no-acl --no-owner -h localhost -U connorwarnock -d db-dev latest.dump

以及随后的错误：

pg_restore: connecting to database for restore
pg_restore: dropping COMMENT EXTENSION plpgsql
pg_restore: dropping EXTENSION plpgsql
pg_restore: dropping COMMENT SCHEMA public
pg_restore: dropping SCHEMA public
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 6; 2615 2200 SCHEMA public whgnwlkesexkyo
pg_restore: [archiver (db)] could not execute query: ERROR:  cannot drop schema public because other objects depend on it
DETAIL:  extension hstore depends on schema public
HINT:  Use DROP ... CASCADE to drop the dependent objects too.
Command was: DROP SCHEMA public;

pg_restore: creating SCHEMA public
pg_restore: [archiver (db)] could not execute query: ERROR:  schema "public" already exists
Command was: CREATE SCHEMA public;



pg_restore: creating COMMENT SCHEMA public

没有数据被导入。似乎公共架构导致了问题（我手动删除了架构并再次尝试，但无济于事）。也许 hstore 扩展引起了麻烦？关于如何避免这些错误的任何其他想法？

Answer 1

看起来您template1包含hstore扩展名和可能的其他更改。

我建议从包含基本默认数据库的只读模板删除db_dev并重新创建它。template0

createdb -T template0 dev_db
