For recurring synchronization and conversion processes, use the Built-in Scheduler. Version: 4. Release Date: Sept. Version: 3. Release Date: March 31, Release Date: Nov. Specifying parameters for destination database looks like the same as for source.
That means any specified database from a pair can be set up as a source or destination. Besides, the same type of database may be set up both as a source or destination. To connect to Cloud database instances, use the same settings as you do for traditional on-premises databases. At the next step, you can specify precisely which tables, fields, indices, views you want to transfer to the PostgreSQL destination database.
Check out our articles about Custoimzation and configuration. The database typically constrains certain relations on the data that cannot be violated. On the customization step, a smart error checker verifies all possible Data integrity and Referential integrity issues and highlights them, if any, before performing a migration. However, you can manually change the data types for the entire database globally using the "Global mapping" or individually for each field.
Check out Smart error checker. Errors and Warnings for more information. Once you configure source and destination databases for migration in the previous steps, you can start the actual conversion or synchronization process. However, to keep this process as clear as possible, this tutorial describes setting up a different PostgreSQL role that authenticates with a password rather than with the ident method.
Run the following command on your Postgres server to create a new role. Note the -P flag, which tells createuser to prompt you to enter a password for the new role:.
You may first be prompted for your sudo password. The script will then prompt you to enter a name for the new role. Following that, createuser will prompt you to enter and confirm a password for this role. Lastly, the script will ask you if the new role should be classified as a superuser. Because of this, the superuser privilege should not be used lightly, and the PostgreSQL documentation recommends that you do most of your database work as a non-superuser role.
However, because pgLoader needs broad privileges to access and load data into tables you can safely grant this new role superuser privileges. PostgreSQL comes with another useful script that allows you to create a database from the command line. Since pgLoader also needs a target database into which it can load the source data, run the following command to create one. Additionally, replace password with a secure password or passphrase:. At this point, you have a dedicated MySQL user that can access the source database from your Postgres machine.
Accordingly, you can resolve this issue by adding the ca. To do this, copy over the ca. Note that you must also rename these files so they have the. Following this, run the update-ca-certificates command. See the official MySQL documentation for details. This includes the pgloader command and two connection strings , the first for the source database and the second for the target database. Using the parameters defined earlier in this tutorial, you can migrate your MySQL database using a command with the following structure.
Be sure to replace any highlighted values to align with your own setup:. Then run the following query to test whether the migrated data is stored in your PostgreSQL database:. This is called a qualified name. See the next step for an example of how to do this. In the context of pgLoader, a load file , or command file , is a file that tells pgLoader how to perform a migration.
The complete list of clauses that one can add to a load file and what they do can be found in the official pgLoader documentation. To use it, include the name of the file as an argument to the pgloader command:. Note that if you plan to use a load file to migrate data held on one database to another located on a separate machine, you will still need to adjust any relevant networking and firewall rules in order for the migration to be successful.
All you need is to run the migration command from a Linux user profile with access to the root MySQL user:. Assuming you have a CSV file of data named load. The documentation says that the output is just "more compatible". It generates a sql file, but it can't be imported into pg.
Try this one , it works like charm!! Sehdev R. Sehdev 2 2 silver badges 10 10 bronze badges. Zero effect. It didn't change anything in the sql query at all, and the query had a "left " in it. That should have been converted to a "substring ". Install the mysql2psql gem using [sudo] gem install mysql2psql. Create a config file by running mysql2psql. You'll see an error but a mysql2psql.

I used this and it worked well for me. Installation on other platforms To install pgloader on Windows , you can use the Windows Subsystem for Linux.
