Question

我正在尝试做rake db:schema:load，但是遇到错误，看来问题出在enable_extension("pg_repack")步骤上：

rake db:schema:load --trace
** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment

Tasks: TOP => db:schema:load

我正在使用Postgres 9.6.6：

which postgres
/usr/local/Cellar/postgresql@9.6/9.6.6/bin/postgres

有什么想法可以让pg_repack工作吗？

编辑：

运行pgxn install pg_repack时得到以下提示：

但是当我运行psql -c "CREATE EXTENSION pg_repack" tr_dev时，仍然收到此消息：

ERROR:  could not open extension control file "/Applications/Postgres.app/Contents/Versions/9.6/share/postgresql/extension/pg_repack.control": No such file or directory

Answer 1

此错误表明pg_repack不存在。首先检查您的目录以查看pg_repack是否存在，但错误仍然存在，您可以尝试

使用DROP EXTENSION pg_repack删除pg_repack或仅删除重新打包模式。

1）从

下载新的pg_repack扩展名

pg repack download

2）$ pgxn install pg_repack

3）$ cd pg_repack $ make $ sudo make install

4）安装后，将pg_repack扩展名加载到要处理的数据库中。 pg_repack被打包为扩展，因此您可以执行：

$ psql -c "CREATE EXTENSION pg_repack" -d your_database
