---------------------------------

             Summary: PostgreSQL - Large Objects may not be used in auto-commit mode.
                 Key: TEIID-3785
                 URL: https://issues.jboss.org/browse/TEIID-3785
             Project: Teiid
          Issue Type: Bug
          Components: JDBC Connector
    Affects Versions: 8.11.3
            Reporter: Tom Arnold
            Assignee: Steven Hawkins


Using Teiid 8.11.3 with PostgreSQL 9.1 and PostGIS. Doing a simple query with a spatial filter causes this stacktrace in the log and 0 results to be returned.

{code}
select item_id from items where st_interesects(footprint, st_geomfromtext('point(0 0)',4326));
{code}

It looks like the issue is binding the WKB blob. Overriding the PostgreSQL translator and setting {{useStreamsForLobs()}} to {{true}} seems to fix the issue.
