Re: keeping images in a bytea field on AWS RDS

I am using postgresql on RDS. I need to upload an image to the table. I understand that I need to set the PGDATA directory and place the image file in it, before setting the path in the bytea field. But how do I set PGDATA if I don't have the ability to set an environment variable, and don't have access to the following on an AWS controlled installation?

$ initdb -D /usr/local/pgsql/data 

or

pg_ctl -D /usr/local/pgsql/data initdb
