postgresql-extension google-libphonenumber

pg-libphonenumber's Introduction

`pg_libphonenumber`

A (partially implemented!) PostgreSQL extension that provides access to Google's libphonenumber

Project status

This extension is in an alpha state. It's not complete or tested enough for critical production deployments, but with a little help, we should be able to get it there.

Synopsis

CREATE EXTENSION pg_libphonenumber;
SELECT parse_packed_phone_number('03 7010 1234', 'AU');
SELECT parse_packed_phone_number('2819010011', 'US');

CREATE TABLE foo ( ph packed_phone_number );

Installation

Debian/Ubuntu

First you'll need to install libphonenumber-dev and the corresponding postgresql-server-dev package.

sudo apt-get update && sudo apt-get install \
    build-essential \
    postgresql-server-dev-9.6 \
    libphonenumber-dev

Then clone this repository and build.

git clone https://github.com/blm768/pg-libphonenumber
cd pg-libphonenumber
make
sudo make install

Running tests

For convenience, we provide a Docker image that sets up a test environment. Run the script ./run-tests.sh to build and run the image.

pg-libphonenumber's Issues

Collation

We need to define a sane collation order for ShortPhoneNumber objects. Right now, we're just ordering by the packed binary data, but that won't always match the natural collation order of phone numbers.

Tag and release a version

I would like to package this project in Homebrew, and that requires a publicly released version of the project. I already wrote the formula file, so it should be pretty easy to get this merged once we have a published version!

Still being developed?

Active or dead? This is a great idea. Any progress on this? Going to move it out of Alpha?

Support TOAST for PhoneNumber type

We'll probably want the PhoneNumber type to be TOAST-able, as it's variable-length.

Handle longer numbers

As per point 16 of the document "Falsehoods Programmers Believe About Phone Numbers", we'll eventually need to handle phone numbers longer than 15 digits.

New Project Idea

Hi @blm768, just wondering are you available to work on a new postgresql extension?

If yes, do provide me your email address. Thanks.

Solidify use cases

The original use case for this project involved improving type safety of phone number storage and making it more compact. With the realization that a fixed-size format was inadequate, development has moved toward a new variable-length PhoneNumber type, which, although more compact than raw strings, doesn't provide major space savings. On top of that, I realized that applications which store phone numbers in a database tend to do their own parsing and validation on the front end, which somewhat reduces the impact of the type safety advantanges.

At some point, the advantages of having a dedicated PhoneNumber type would need to outweigh the costs (i.e. potential for instability, administrative overhead for installation and maintenance, etc.) for this library to see meaningful use.

With all that being said, what additional use cases exist for libphonenumber bindings in PostgreSQL? There's likely something I'm not thinking of.

Compile errors, namely about 'int64' being ambiguous

Here is the result of a compile, on macOS:

I know next to nothing about C++ and building PG extensions, so I won't be of much help here, but I hope this helps.

Special characters

We don't currently have a good way of encoding special characters (i.e. * and #) in a ShortPhoneNumber. We'll probably need that eventually.

I am using postgres 11 so that could be the issue? Is there a way to support 11 or is 9.4 the only supported version? Searching online, I find this on a different project which leads to this snippet but copying that into the Makefile doesn't help. I don't know enough to understand the messages.

Is this still in alpha?

I notice there hasn't been development for a while, is this still in alpha?

Compile failure related to cmath

I was able to build this project in the past, and now I can't. I'm not sure if the error is caused by changes in the project, or changes in my development environment.

I was able to work around that by adding /usr/local/include to the list of include paths for C++ -- I installed libphonenumber via Homebrew, and Homebrew keeps everything under /usr/local.

After I fixed that, I ran into a different issue:

I have not found a workaround for this issue. It appears that the latest development toolchain on macOS has problems with the <cmath> headers -- I think this is the same problem.

I'm running macOS 10.14.6, Xcode 11.2.1. Not sure what other debugging information would be useful.
