Unable to use parameterized query with node pg module and Teiid/JBoss VDB

When using node pg 6.4.1 in a node application to connect to a JBoss VDB with Teiid, we are unable to successfully return data with a parameterized query.

Example from node js application (failure):

client.query("SELECT * FROM records WHERE recordType = $1", ['TYPE1'], function(err, result)

{ done(); })

The above code will actually retrieve rows of data, but the connection will be terminated unexpectedly from the JBoss side, thus resulting in a failure. We can confirm though that the parameter is properly inserted into the variable, and rows of data can be retrieved without issue.

Also, we have confirmed that when sending a static query, we are able to successfully return data without JBoss terminating the connection. We found this approach from the Teiid blog: http://teiid.blogspot.com/2013/02/access-teiid-from-nodejs.html

Example from node js application (success):

client.query("SELECT * FROM records WHERE recordType = 'TYPE1'", function(err, result) { done(); }

)

Is there something different about a parameterized query vs. a static query that may cause this issue?

Are you aware of other individuals who have successfully used parameterized queries with the node pg module and Teiid/JBoss VDB?

Is it possible that how the ODBC settings for Teiid are configured may have an impact on parameterized queries vs. static queries?

Thank you so much for all your help!
