There are some places in the frontend where we use camelCase aliases for columns in an SQL query, but PostgreSQL always returns results with lower-case keys. One of the problems it causes is that a template.get request in 2.2 returns unnecessary data:

{
"output": "refer",
"parentTemplateids": 10050,
"limit": 1
}

{
    "jsonrpc": "2.0",
    "result": [
        {
            "parenttemplateid": "10050",
            "templateid": "10001"
        }
    ],
    "id": 1
}

It may cause other problems too. We'll need to check all usages of aliases in the frontend and convert them to lower case. As far as I understood, the C side uses only lower-case aliases, so it shouldn't have any problems.
