如何将数据从非bdr pgsql迁移到bdr pgsql

Question

我有fusionpbx与简单的pgsql工作...现在我已经创建了HA fusionpbx与bdr pgsql，它工作正常，但我不知道如何将数据从非bdr pgsql迁移到bdr pgsql ...

Answer 1

pg_dump worked for me.

pg_dump $non_bdr_db > db.sql
psql $bdr_db < db.sql

Although if you have some fancy extensions (in my case it's PostGIS) you might want to restore the database from the backup first (separately on each and every node of your BDR cluster) and then enable the BDR extension.
