title: Npgsql <-> Entity Framework Error 57014
body: <p>i use the following code for accessing a database table:</p>
  
  <pre><code> DbConnection dbConnection = new NpgsqlConnection("PORT=5432;TIMEOUT=15;POOLING=True;MINPOOLSIZE=1;MAXPOOLSIZE=20;COMMANDTIMEOUT=20;COMPATIBLE=2.2.4.3;HOST=localhost;DATABASE=postgres;USER ID=yep;PASSWORD=thisisnottherealone;-)");
  
   DB = new DataAccessContext(dbConnection);
   IQueryable&lt;Customer&gt; customers = from c in DB.Customers
                          select c;
   List&lt;Customer&gt; test =  customers.ToList();
   ...
  </code></pre>
  
  <p>The problem is that there is an error message: "NpgsqlException - ERROR: 57014"</p>
  
  <p>The query itself takes an irritating long amount of time.</p>
  
  <p>Most of the time it seems that objekts are created by EF.</p>
  
  <p>Is there some possibility to speed this up and don't get the exception? (it is not an alternative to get a subset of data)</p>
  
  <p>Is there something configuratable like a caching by EF?</p>
