or specify columns ) INSERT INTO -specify columns if necessary SELECT DISTINCT FROM movedrows But you want to move the data into a new table (not an existing one. WITH movedrows AS ( DELETE FROM a USING b WHERE RETURNING a.
Then set the DMS Task's (CDC) recovery checkpoint to correspond with the backup checkpoint of the source. Extract the table and pipe it directly to the target database: pgdump -t tabletocopy sourcedb psql targetdb. For unmatched schema, you should specify columns. If minimal downtime is your ultimate goal, the fastest way to get data to the target would be to upload a backup, restore at the target. You can read more about the mapping rules and how to apply in the aws documentation. in your list, just without this consideration: but this requires the indexes on one table being copied to the other. COPY TO copies the contents of a table to a file, while COPY FROM copies data from a file to a table (appending the data to whatever is in the table already). Follow these steps to export and import your PostgreSQL database. "rule-name": "include-public-schema-only", If you don't have other objects depending on the tables (like views and foreign keys), it's a simple operation to drop the existing table dest and just rename the new table src. COPY TO can also copy the results of a SELECT query. COPY TO copies the contents of a table to a file, while COPY FROM copies data from a file to a table (appending the data to whatever is in the table already). You can use the "%" to include all tables in the schema. COPY moves data between PostgreSQL tables and standard file-system files. If you wanted to sync only tables in a single schema, simply create a rule-type of selection and define the schema in the object-locator section the selection criteria. Table mapping rules can be applied to a source or target endpoint of a Data Migration Task. For example, the COPY TO command outputs the content of a table to a. Using DMS, you can include/exclude based on one or more schemas. The COPY command can import data to Postgres if access to text, CSV, or binary format data. Just curious, if using Aurora, have you looked into cross account synchronization using logical replication? If you are copying between two tables in the same database, you can do something like.
