emailaddr type for PostgreSQL

https://twitter.com/pvh/status/667106073199775744

This is an extension for PostgreSQL that provides a type emailaddr for storing email addresses.

Installation

To build and install this module:

make
make install

or selecting a specific PostgreSQL installation:

make PG_CONFIG=/some/where/bin/pg_config
make PG_CONFIG=/some/where/bin/pg_config install

And finally inside the database:

CREATE EXTENSION emailaddr;

Using

This module provides a data type emailaddr that you can use like a normal type. For example:

CREATE TABLE accounts (
    id int PRIMARY KEY,
    name text,
    email emailaddr
);

INSERT INTO accounts VALUES (1, 'Peter Eisentraut', '[email protected]');

The accepted addresses correspond approximately to the addr-spec production in RFC 5322 (so it's of the type [email protected], but not "Some Name" <[email protected]>).

Helper functions are available for hosts and users, and can be used thus:

SELECT emailaddr_user(email) FROM accounts WHERE emailaddr_host(email) = 'eisentraut.org';
