psycopg2 Python Library for AWS Lambda

======================================

This is a custom compiled psycopg2 C library for Python. Due to AWS Lambda

missing the required PostgreSQL libraries in the AMI image, we needed to

compile psycopg2 with the PostgreSQL `libpq.so` library statically linked

libpq library instead of the default dynamic link.

### Install and setup

``` pip install aws-psycopg2 ```

### Source code : https://github.com/AbhimanyuHK/aws-psycopg2 

### Instructions on compiling this package from scratch

Here was the process that was used to build this package. You will need to

perform these steps if you want to build a newer version of the psycopg2

library.

1. Download the

  [PostgreSQL source code](https://ftp.postgresql.org/pub/source/v9.4.3/postgresql-9.4.3.tar.gz) and extract into a directory.

2. Download the

  [psycopg2 source code](http://initd.org/psycopg/tarballs/PSYCOPG-2-6/psycopg2-2.6.1.tar.gz) and extract into a directory.

3. Go into the PostgreSQL source directory and execute the following commands:

  - `./configure --prefix {path_to_postgresql_source} --without-readline --without-zlib`

  - `make`

  - `make install`

4. Go into the psycopg2 source directory and edit the `setup.cfg` file with the following:

  - `pg_config={path_to_postgresql_source/bin/pg_config}`

  - `static_libpq=1`

5. Execute `python setup.py build` in the psycopg2 source directory.

After the above steps have been completed you will then have a build directory

and the custom compiled psycopg2 library will be contained within it. Copy this

directory into your AWS Lambda package and you will now be able to access

PostgreSQL from within AWS Lambda using the psycopg2 library.
