"Owner" param not working for PostgreSQL.

从提供的 SqlDataProvider 复现开始，使用 PostgreSQL 和 Owner="backoffice"；该 issue 未提供需要首先定位的源文件或测试。跟踪类型提供程序的入口点和现有的 PostgreSQL owner 处理，然后验证复现不再报告 FS3028，并解析所请求的 owner。

Description

The Owner parameter for the connecting to PostgreSQL doesn't seem to work and results in an error.

Repro steps

Connect to a PostgreSQL database like so:

    let [<Literal>] resPath = __SOURCE_DIRECTORY__ + @"..\..\packages\Npgsql.3.1.0\lib\net45\"
    let [<Literal>] dbVendor = Common.DatabaseProviderTypes.POSTGRESQL

    type dbCon = 
        SqlDataProvider<DatabaseVendor = dbVendor,
                        ConnectionString = dbConStr,
                        ResolutionPath = resPath,
                        UseOptionTypes = false,
                        Owner = "backoffice">

    let db = dbCon.GetDataContext()

Actual behavior

I get the following error:

Error	FS3028	The type provider 'FSharp.Data.Sql.SqlTypeProvider' reported an error: Expected provided type named 'SqlDataProvider,DatabaseVendor="2",ConnectionString="Host=xxx; Database=xxx; Username=xxx; Password=xxx; ApplicationName=xxx; MinPoolSize=4; MaxPoolSize=10; Timeout=60; CommandTimeout=600",ResolutionPath="C:\\Users\\xxx\\packages\\Npgsql.3.1.0\\lib\\net45\\",Owner="backoffice"' but provided type has 'Name' with value 'SqlDataProvider,DatabaseVendor="2",ConnectionString="Host=xxx; Database=xxx; Username=xxx; Password=xxx; ApplicationName=xxx; MinPoolSize=4; MaxPoolSize=10; Timeout=60; CommandTimeout=600",ResolutionPath="C:\\Users\\xxx\\packages\\Npgsql.3.1.0\\lib\\net45\",Owner=\"backoffice"'	xxx	C:\Users\xxx\Desktop\xxx\Library1.fs
