InvalidCastException in the PostgreSqlConnectionProvider.CollectTablesToCreate method with npgsql 3.0.3 (PostgreSQL)

Hello,

I'm using npqsql.dll to connect to a PostgreSQL 9.4 database. After upgrading npqsql to 3.0.3 (and upgrading my assemblies to .Net 4.5), an InvalidCastException is thrown in C:\Program Files (x86)\DevExpress 14.2\Components\Sources\DevExpress.Xpo\DevExpress.Xpo\Providers\PostgreSQL.cs on line 454

C#
public override ICollection CollectTablesToCreate(ICollection tables) {  
            Dictionary dbTables = new Dictionary();  
            Dictionary dbSchemaTables = new Dictionary();  
            string queryString = @"select c.relname, c.relkind, n.nspname from pg_class c  
join pg_namespace n on c.relnamespace = n.oid  
where c.relname in({0}) and (c.relkind = 'r' OR c.relkind = 'v')";  
            foreach (SelectStatementResultRow row in GetDataForTables(tables, null, queryString).Rows) {  
                if (row.Values[0] is DBNull) continue;  
                string tableName = (string)row.Values[0];  
                bool isView = (string)row.Values[1] == "v";  
                string tableSchemaName = (string)row.Values[2];  
                dbTables[tableName] = isView;  
                dbSchemaTables.Add(string.Concat(tableSchemaName, ".", tableName), isView);  
            }  

The line

C#
bool isView = (string)row.Values[1] == "v";  

is causing the exception since row.Values[1] is a char.
