This patch does the following: 1) The env scripts have been updated to be tolerant of a NULL configuration file. This occurs when configuration is provided by an external script, such that the actual config.ini file is not used. 2) Enum types have all been given names. This is needed for PostgreSQL script generation. 3) The identifier meetme_confno_starttime_endtime is greater than 30 characters, and hence invalid for Oracle databases. This has been truncated down to meetme_confno_start_end. ........
