I spoke to soon.  Where can I find the DB-API for postgres?  Because the only 
way I can get this to work is using ('%s') and it does not work with (%s).

BTW where I'm doing my testing is with a SELECT statement.

below does not work
mySQL= "Select fieldname from tableName where str_field = %s" % (myVar,)

but this works
mySQL= "Select fieldname from tableName where str_field = '%s' " % (myVar,)
