# PostgreSQL.jl

[![Build Status](https://travis-ci.org/JuliaDB/PostgreSQL.jl.svg)](https://travis-ci.org/JuliaDB/PostgreSQL.jl)  [![Coverage Status](https://img.shields.io/coveralls/JuliaDB/PostgreSQL.jl.svg)](https://coveralls.io/r/JuliaDB/PostgreSQL.jl)  [![codecov.io](http://codecov.io/github/JuliaDB/PostgreSQL.jl/coverage.svg)](http://codecov.io/github/JuliaDB/PostgreSQL.jl)

An interface to PostgreSQL from Julia. Uses libpq (the C PostgreSQL API) and obeys the [DBI.jl protocol](https://github.com/JuliaDatabases/DBI.jl).

## Maintenance Notice

I can no longer spend work time on this so this project is in maintenance mode (accepting PRs and attempting to resolve issues). New code on the `dbapi` branch (https://github.com/JuliaDatabases/DBAPI.jl) represents the most recent work, which I will continue if I am in a position to do so again.

## Usage

```julia

using DBI

using PostgreSQL

conn = connect(Postgres, "localhost", "username", "password", "dbname", 5432)

stmt = prepare(conn, "SELECT 1::bigint, 2.0::double precision, 'foo'::character varying, " *

					 "'foo'::character(10);")

result = execute(stmt)

for row in result

	# code

end

finish(stmt)

disconnect(conn)

```

### Block Syntax

```julia

using DBI

using PostgreSQL

connect(Postgres, "localhost", "username", "password", "dbname", 5432) do conn

	#code

end

```

## Requirements

* [DBI.jl](https://github.com/JuliaDatabases/DBI.jl)

* [DataFrames.jl](https://github.com/JuliaStats/DataFrames.jl) >= v0.5.7

* [DataArrays.jl](https://github.com/JuliaStats/DataArrays.jl) >= v0.1.2

* libpq shared library (comes with a standard PostgreSQL client installation)

* Julia 0.4

Tests require a local PostgreSQL server with a postgres user/database (installed by default with PostgreSQL server installations) with trusted authentication from localhost.

## Systems

* Tested on Funtoo Linux and Windows 8

* Should work on other systems provided libpq is avaiable (please file an issue if this is not the case)

## TODO (soon)

* Implement more default PostgreSQL type handling

* Test type handling overrides

* More comprehensive error handling and tests

* Support for COPY

## TODO (not soon)

* Asynchronous connection support

* Asynchronous Julia for handling asynchronous connections

* Testing and compatibility with multiple versions of PostgreSQL and libpq
