背景

在Gitlab迁移恢复数据出现must be owner of extension plpgsql解决方法；在做gitlab迁移时，按正常Gitlab备份数据gitlab-rake gitlab:backup:create，没问题，数据显示正常，但是在恢复的时候却出现报错。

Gitlab恢复数据出现错误提示：

Restoring PostgreSQL database gitlabhq_production ... ERROR:  must be owner of extension pg_trgm
ERROR:  must be owner of extension btree_gist
ERROR:  must be owner of extension btree_gist
ERROR:  must be owner of extension pg_trgm

解决方案

1. 修改postgresql配置

   $ vim /var/opt/gitlab/postgresql/data/postgresql.conf
   listen_addresses = '*'

   最下面新增两行

   $ vim /var/opt/gitlab/postgresql/data/pg_hba.conf
   local all all trust
   host all all 127.0.0.1/32 trust

2. 重启gitlab服务

   $ gitlab-ctl restart
   ok: run: logrotate: (pid 29367) 1s
   ok: run: nginx: (pid 29371) 0s
   ok: run: postgresql: (pid 29389) 0s
   ok: run: redis: (pid 29391) 0s
   ok: run: sidekiq: (pid 29404) 0s
   ok: run: unicorn: (pid 29413) 0s

3. 修改gitlab账号为超级用户

   $ su - gitlab-psql
   $ /opt/gitlab/embedded/bin/psql -h 127.0.0.1 gitlabhq_production
   psql (9.2.8)
   Type "help" for help.

   gitlabhq_production=# ALTER USER gitlab WITH SUPERUSER;
   ALTER ROLE
   gitlabhq_production=# \q

再次恢复数据已不报错
