How to import PostgreSQL data into Amazon RDS?
To import PostgreSQL data into a DB instance, follow the information in the Importing data into PostgreSQL on Amazon RDS section. The following are the common management tasks you perform with an Amazon RDS for PostgreSQL DB instance, with links to relevant documentation for each task.
Can you create a DB instance in Amazon RDS?
Amazon RDS supports DB instances running several versions of PostgreSQL. You can create DB instances and DB snapshots, point-in-time restores and backups. DB instances running PostgreSQL support Multi-AZ deployments, read replicas, Provisioned IOPS, and can be created inside a VPC.
How to connect Amazon Redshift to Amazon PostgreSQL?
Launch an Amazon Redshift cluster. Launch an RDS PostgreSQL (9.5+) instance in the same Availability Zone as the cluster in Step 1. Configure the VPC security group for the Amazon Redshift cluster to allow an incoming connection from the RDS PostgreSQL endpoint.
What kind of architecture does RDS PostgreSQL use?
RDS PostgreSQL uses a row-based architecture, which offers advantages when the workload is selecting, inserting, updating or deleting a small number of rows at a time, which is typical for OLTP. Amazon Redshift also uses a massively parallel processing (MPP), shared-nothing architecture.
Suppose that you have an existing PostgreSQL deployment that you want to move to Amazon RDS. The complexity of your task depends on the size of your database and the types of database objects that you’re transferring. For example, consider a database that contains datasets on the order of gigabytes, along with stored procedures and triggers.
How to import data into a PostgreSQL database?
Create the target PostgreSQL DB instance using either the Amazon RDS console, AWS CLI, or API. Create the instance with the backup retention setting set to 0 and disable Multi-AZ. Doing so allows faster data import. You must create a database on the instance before you can dump the data.
How to move data from Amazon EC2 to PostgreSQL?
The PostgreSQL command pg_dumpall requires super_user permissions that are not granted when you create a DB instance, so it cannot be used for importing data. If you have data in a PostgreSQL server on an Amazon EC2 instance and want to move it to a PostgreSQL DB instance, you can use the following process.
How to create a data dump in PostgreSQL?
The pg_dump utility uses the COPY command to create a schema and data dump of a PostgreSQL database. The dump script generated by pg_dump loads data into a database with the same name and recreates the tables, indexes, and foreign keys.
