New Revision: 839

Modified:
   trunk/server/src/main/java/com/metamatrix/common/log/DbLogWriter.java
Log:
JBEDSP-803 - this is related to the postgres issue, changed to determine the quote at the initialization of the class instead on every call (getDatabaseMetadata() can be expensive is called on every write)
