title: Writing to specific schemas with RPostgreSQL
body: <p>I'm using <a href="http://code.google.com/p/rpostgresql/" rel="noreferrer">RPostgreSQL</a> to read and write data. Reading from any schema works perfectly, but I'm not able to write to non-public schemas. For example, the following code places a table in the <code>public</code> schema, with the name <code>myschema.tablex</code></p>
  
  <pre><code># write dataframe to postgres 
  drv &lt;- dbDriver("PostgreSQL")
  con &lt;- dbConnect(drv, host="localhost", user="postgres", password="zzzz", dbname="mydatabase", port="5436")
  if(dbExistsTable(con,"myschema.tablex")) {
    dbRemoveTable(con,"myschema.vkt_tablex")}
  dbWriteTable(con,"myschema.tablex", dataframe, row.names=F)
  </code></pre>
  
  <p>What I want to do, is to place the table <code>tablex</code> in the schema <code>myschema</code>. I've also tried to name the schema in the connection: <code>dbname="mydatabase.myschema"</code> and trying the argument <code>schemaname</code> which I saw referred to in an earlier bug.</p>
  
  <p>None of these approaches work, so I'm wondering if there is another method that I can use.</p>
