Easy way to use a PostgreSQL database (and the HSTORE feature) from Go.

Online API Documentation

------------------------

[godoc.org](http://godoc.org/github.com/xyproto/simplehstore)

Features and limitations

------------------------

* Requires PostgreSQL 9.1 or later.

* Requires Go 1.10 or later.

* Supports simple use of lists, hashmaps, sets and key/values.

* Deals mainly with strings.

* Uses the [pq](https://github.com/lib/pq) package.

* Modeled after [simpleredis](https://github.com/xyproto/simpleredis).

* Uses SQL queries with HSTORE for the KeyValue and HashMap types.

* Uses regular SQL for the List and Set types.

Sample usage

------------

~~~go

package main

import (

    "log"

    db "github.com/xyproto/simplehstore"

)

func main() {

    // Check if the local db service is up

    if err := db.TestConnection(); err != nil {

        log.Fatalln("Could not connect to local database. Is the service up and running?")

    }

    // Create a Host, connect to the local db server

    host := db.New()

    // Connecting to a different host/port

    //host := db.NewHost("server:5432/db")

    // Connect to a different db host/port, with a username and password

    // host := db.NewHost("username:password@server/db")

    // Close the connection when the function returns

    defer host.Close()

    // Create a list named "greetings"

    list, err := db.NewList(host, "greetings")

    if err != nil {

        log.Fatalln("Could not create list!")

    }

    // Add "hello" to the list, check if there are errors

    if list.Add("hello") != nil {

        log.Fatalln("Could not add an item to list!")

    }

    // Get the last item of the list

    if item, err := list.GetLast(); err != nil {

        log.Fatalln("Could not fetch the last item from the list!")

    } else {

        log.Println("The value of the stored item is:", item)

    }

    // Remove the list

    if list.Remove() != nil {

        log.Fatalln("Could not remove the list!")

    }

}

Testing

-------

* A PostgreSQL server must be up and running locally for `go test` to work, and a database named `test` must exist.
