For example: pg_dump -h my-source-server-name -U source-server-username -Fc -d source-databasename -f Z:\Data\Backups\my-database-backup.dump Take the backup with the -Fc switch, so that you can perform the restore in parallel to speed it up. To minimize the time required to complete the migration, consider using the following parameters with the backup and restore commands.įor detailed syntax information, see pg_dump and pg_restore. One way to migrate your existing PostgreSQL database to Azure Database for PostgreSQL is to back up the database on the source and restore it in Azure. Here's an example for how to use this pg_restore for Flexible Server: pg_restore -v -no-owner -host=.com -port=5432 -username=mylogin -dbname=mypgsqldb testdb.dump Here's an example for how to use this pg_restore for Single Server: pg_restore -v -no-owner -host=.com -port=5432 -dbname=mypgsqldb testdb.dump In this example, restore the data from the dump file testdb.dump into the database mypgsqldb, on target server .com. In Linux or Bash, run the command export PGSSLMODE=require before running the pg_restore command. Please specify SSL options and retry." In the Windows command line, run the command SET PGSSLMODE=require before running the pg_restore command. Without TLS, the error might read: "FATAL: SSL connection is required. If your PostgreSQL server requires TLS/SSL connections, but doesn't have them, set an environment variable PGSSLMODE=require so that the pg_restore tool connects with TLS. On Azure Database for PostgreSQL servers, TLS/SSL connections are on by default. For more information, see the PostgreSQL documentation. Including the -no-owner parameter causes all objects created during the restore to be owned by the user specified with -username. pg_restore -v -no-owner -host= -port= -username= -dbname=. Restore the data into the target databaseĪfter you've created the target database, you can use the pg_restore command and the -dbname parameter to restore the data into the target database from the dump file. dumpįor example, if you have a local server and a database called testdb in it, run: pg_dump -Fc -v -host=localhost -username=masterlogin -dbname=testdb -f testdb.dump To back up an existing PostgreSQL database on-premises or in a VM, run the following command: pg_dump -Fc -v -host= -username= -dbname= -f. pg_dump and pg_restore command-line utilities installed.Ĭreate a dump file that contains the data to be loaded.An Azure Database for PostgreSQL server, including firewall rules to allow access.To step through this how-to guide, you need: Then use pg_restore to restore the PostgreSQL database from an archive file created by pg_dump. You can use pg_dump to extract a PostgreSQL database into a dump file. Azure Database for PostgreSQL - Single ServerĪzure Database for PostgreSQL - Flexible Server
