What is PostgreSQL?
PostgreSQL, also known as Postgres, is a robust open-source relational database that employs and extends the SQL language and incorporates numerous features to store and scale the most complex data workloads safely. It dates back to 1986 and has started as part of the POSTGRES project at the University of California at Berkeley; PostgreSQL currently holds an active and growing ecosystem of developers and tools.
An enterprise-class database, Postgre works on the most widespread operating systems – such as Linux and Unix distributions, Windows, Mac OS X.SQL. PostgreSQL enables its users to manage data, regardless of its extensive database.
One major difference between PostgreSQL and standard relational database systems that make it highly extensible is that PostgreSQL stores vast amounts of data in its catalogs. It keeps the information about data types, functions, access methods, etc.
Key Features of PostgreSQL
PostgreSQL has become one of the most sought-after Databases Management Systems due to the following eye-catching features:
- Enhanced Data Integrity: PostgreSQL assures Data Integrity via Primary Keys, Foreign Keys, Explicit Locks, Advisory Locks, & Exclusion Constraints.
- Multiple Data Types: PostgreSQL allows you to work with a broad range of datasets. It is compatible with several data types such as INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, TIMESTAMP, etc.
- Data Security: You can rest assured with several layers of Data Authentication and Protection layers. It provides different authentications such as Lightweight Directory Access Protocol(LDAP), Generic Security Service Application Program Interface (GSSAPI), SCRAM-SHA-256, and Security Support Provider Interface (SSPI), etc. It also provides a robust Access Control System along with Column & Row-level security.
- Reliability: PostgreSQL provides a reliable environment with special features such as Multi-Version Concurrency Control (MVCC), point in time recovery, tablespaces, Asynchronous Replication, online/hot backups, and write-ahead logging.

What is MySQL?
MySQL is a freely available open-source Relational Database Management System (RDBMS) that is based on Structured Query Language (SQL). It has been developed and is supported by the Oracle Corporation. It is typically used to create and manage web databases, however, its application has a wide range of purposes, including data warehousing, e-commerce, and logging applications.
MySQL is ideal for both small and large applications as it can store anything from single records to a large inventory of products. It is very fast, reliable and delivers efficient features to meet its users’ requirements, and holds a user-friendly interface compared to other software, making it popular.
Key Features of MySQL
MySQL is widely used by organizations like Facebook, Flickr, Twitter, Wikipedia, and YouTube. This is due to the following set of MySQL’s eye-catching features:
- Ease of Operation: With MySQL, you can work with a diverse set of programming languages such as PHP, PERL, C, C ++, and JAVA. It also provides a set of intuitive tools to simplify time-consuming tasks such as Server Management, Reporting, and Data Analysis. Allowing you to work with a broader range of datasets, MySQL offers full support for several Data structures, JSON and Geospatial data, as well as Logical, Numeric, Alphanumeric, Date, and Time data types.
- First-rate Performance: MySQL delivers best-in-class query performance across a variety of clustered servers. It provides a fast-loading utility with a separate memory cache and table index partitioning. MySQL can also efficiently handle fluctuating workloads and process large volumes of data at optimal speeds. This allows you to store more than 50 million rows of data in a table with a table’s default file size limit of 4 GB. However, depending on the configuration of the operating system, this can be increased to a theoretical limit of 8 million terabytes (TB).
- Open-Source: MySQL is under the GNU General Public License (GPL), which means it will always be freely available. It provides you the freedom to customize it on Oracle’s Open-Source MySQL codebase based on your needs. Since it is an Open-Source software, a large community has grown that regularly enriches MySQL’s documentation and its online support culture.
- Localization: To make it user-friendly, MySQL supports multiple character sets, including latin1 (cp1252), german, big5, ujis, and more. You can also set the error message language that the server provides to the client. The MySQL Server Time can also be dynamically changed with the ability to set specific time zones for individual clients.
- Data Security: MySQL provides you full control over the Data Access Control settings. Robust mechanisms such as Access Privilege Systems and User Account Management allow you to regulate who can view or use your MySQL data. MySQL sets the highest standard with Host-based Verification and Password Encryption.
- You need to have a Google Cloud account. If you don’t have one, you will need to have one created.
- Open the project selector page from the Google Cloud Console and either select or create a Google Cloud project.
- Ensure that billing is enabled for your Cloud project. Even if you’re using the Free option, billing must be enabled for the project, or you might encounter connection issues.
- Enable the Database Migration Service API. Refer to Google’s documentation for more info.
- Furthermore, you will need to have the Database Migration Admin role assigned to your user account.

GCP PostgreSQL MySQL Connection Step 1: Set up a Connection Profile
The completion of a GCP PostgreSQL MySQL connection profile will create a record that collects information related to the source database. DMS will make use of this info to move data from your GCP PostgreSQL database to the Cloud SQL for MySQL database instance.
- Step 1: Open the Database Migration Service Connection profile page in the Google Cloud Console and click on the CREATE PROFILE button.
- Step 2: Open the Source database engine drop-down list and choose the classification type of your source database. In our case, select the A standalone MySQL instance (MySQL) option.
- Step 3: Provide the following details:
- Under the Connection profile name field, provide a name for the connection profile for your source database.
- Keep the auto-generated Connection profile ID.
- Type the Connectivity info:
- In case you are replicating from a self-hosted database, you will have to supply the Hostname or IP address, as well as the Port, to access the host. (MySQL’s default port is 3306.)
- In case you’re replicating from a Cloud SQL database, just pick the Cloud SQL instance from the drop-down list.
- Provide the Username and Password so you can connect to the source instance.
- (Optional) In case you are looking to move sensitive data over a public network (by using IP allowlists), it is highly recommended to use SSL/TLS encryption; otherwise, you can just maintain the default value of None.
- Step 4: Under the Connection profile region section of the page, choose the region where you like to have your connection profile saved and click on the CREATE button.
GCP PostgreSQL MySQL Connection Step 2: Create a Migration Job
- Step 1: In the Google Cloud Console, open the Database Migration Service Migration jobs page.

During this GCP PostgreSQL MySQL Connection step, you will need to choose the networking method that you’ll use to connect the source and destination databases.
- Step 1: Click on the Connectivity method to open a drop-down list and choose the IP allowlist as the networking method.
- Step 2: In case the IP address isn’t already pre-populated, you will need to copy the Cloud SQL for MySQL’s outgoing IP address and use it to set up the network firewall. Skipping this step will prevent the source database server from accepting connections from this IP address.
- Step 3: Under the firewall rules, you will need to set up an Inbound rule that will permit connections on port 3306 coming from the destination Cloud SQL for MySQL IP address.
- Step 4: Click on the CONFIGURE & CONTINUE button to finish the connection profile setup.
GCP PostgreSQL MySQL Connection Step 4: Test your Migration Job
- Step 1: Click TEST JOB to check whether the migration job is valid. If it was successful, you should get a “Tests passed successfully!” notification.
- Step 2: In case the test did not pass, you can address the problem and return to re-test.
GCP PostgreSQL MySQL Connection Step 5: Start the Migration
- Step 1: Click on the CREATE & START JOB button and click START to start the migration.
- Step 2: Under the Migration jobs page, you can check the status of your migration job.
- Step 3: Confirm the migration job.
- Step 4: During this stage, you will ensure that Database Migration Service used the migration job to move data from the source database instance to the destination Cloud SQL for MySQL database instance.
- Step 5: Proceed to the SQL Instances page in the Google Cloud Console and click the read replica of the migration task..
- Step 6: In the upper-right corner of the page, there is an Activate Cloud Shell icon. Just click on it
- Step 7: Next, a Google Cloud Shell will be prompted, and you have to click on Enter.
- Step 8: Connect to the destination Cloud SQL database instance for MySQL.
- Step 9: An enter password page will be prompted during the next step. Here, you will have to enter the password you set up earlier or the one automatically generated.
- Step 10: At the MySQL prompt, ensure that you will
- Enter show databases; to get a list of the databases and confirm if the source database instance is listed
- Use the source_database_instance_name; as you will want to be able to see the tables related to this database instance.
- Enter show tables; to review the tables of this instance.
- Enter select * from table_name; to go over the information that’s replicated in the source database instance.
- Step 11: Next, check that the information in the table is correct, which confirms that the DMS has migrated the data.
- Step 12: When the replication delay moves toward zero, you can stop all writes.
