s3_fdw provides a foreign-data wrapper (FDW) for Amazon S3 files, using the builtin COPY format.
To build it, just do this:
make
make install
If you encounter an error such as:
make: pg_config: Command not found
Be sure that you have pg_config installed and in your path. If you used a
package management system such as RPM to install PostgreSQL, be sure that the
-devel package is also installed. If necessary tell the build process where
to find it:
env PG_CONFIG=/path/to/pg_config make && make installcheck && make install
Once make install is done, connect to your database with psql or other client
and type
CREATE EXTENSION s3_fdw;
then you'll see the FDW is installed. With the FDW, create server, user mapping, foreign table. You'll need Amazon S3 access key ID and secret access key to authenticate private access to your data. Consult AWS documentation for those keys. The access information is stored in user mapping. Foreign tables stores options for COPY as well as hostname, bucketname and filename.
The s3_fdw data type depends on libcurl and openssl. You need those developer
packages installed in the system path.
