// Package postgres for session provider
//
// depends on github.com/lib/pq:
//
// go install github.com/lib/pq
//
//
// needs this table in your database:
//
// CREATE TABLE session (
// session_key char(64) NOT NULL,
// session_data bytea,
// session_expiry timestamp NOT NULL,
// CONSTRAINT session_key PRIMARY KEY(session_key)
// );
//
// will be activated with these settings in app.conf:
//
// SessionOn = true
// SessionProvider = postgresql
// SessionSavePath = "user=a password=b dbname=c sslmode=disable"
// SessionName = session
//
//
// Usage:
// import(
// _ "github.com/astaxie/beego/session/postgresql"
// "github.com/astaxie/beego/session"
// )
//
// func init() {
// globalSessions, _ = session.NewManager("postgresql", ``{"cookieName":"gosessionid","gclifetime":3600,"ProviderConfig":"user=pqgotest dbname=pqgotest sslmode=verify-full"}``)
// go globalSessions.GC()
