Unable to import s3 data to RDS(Postgresql) using aws_commons extension

Question

I am trying to import s3 file(CSV file) to Postgre sql rds instance. I am running s3 import queries from rds instance as per AWS docs but i am getting below error

ERROR: syntax error at or near ":" LINE 5: :'s3_uri', ^ SQL state: 42601 Character: 76

Query i used for downloading s3 file is below:

SELECT aws_s3.table_import_from_s3( 't1', '', '(format csv)', :'s3_uri', );

Running query as per AWS doc: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL.Procedural.Importing.html#USER_PostgreSQL.S3Import.Overview

SELECT aws_s3.table_import_from_s3( 't1', '', '(format csv)', :'s3_uri', );

Answer 1

:' is not a valid syntax. :'s3_uri' , including the leading colon, need to be replaced with a s3 URI. When you are done, there should be no literal colon there outside the quotes.

Answer 2

I had the same error. Solved it with these steps:

1. upgrade postgres to version 14.4 (though 12.4 also works )
2. install aws_commons CREATE EXTENSION aws_s3 CASCADE;
3. run

SELECT aws_commons.create_aws_credentials('access_key','secret_key') as credentials;

SELECT aws_commons.create_s3_uri('bucket_name', 'file_name.csv') AS s3_uri_1 \gset

SELECT aws_s3.table_import_from_s3('table_name','','(format csv)',:'s3_uri_1');

Answer 3

Try add \n before:

SELECT aws_s3.table_import_from_s3( 't1', '', '(format csv)', 
:'s3_uri', );
