[teiid-issues] [JBoss JIRA] (TEIID-4877) Boolean syntax is broken on pg 9.5 data sources

[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-4877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-4877.
-----------------------------------
    Resolution: Done


Added missing parens to the sql generating logic.  This was always needed regardless of postgresql as the Teiid sql parser needed the parens as well.

A corresponding change may be needed on the designer side as well.
