Changes for Postgres

[hiven]

Hi,

I have put the schema into a postgres database and updated the config to reflect it is a postgres DB. It fails to connect. Is there any reason why making this a postgres database should cause it to break?

'```
DB_TYPE' => 'pgsql',
'DB_HOST' => 'manny.db.elephantsql.com',
'DB_NAME' => 'sklgimir',
'DB_USER' => 'sklgimir',
'DB_PASS' => 'PASSWORD',
'DB_PORT' => '5432',
'DB_CHARSET' => 'utf8',
