ATTENTION: It appears you are using PostgreSQL and you have identifier-quoting turned on. It is suggested that you disable identifier quoting when using PostgreSQL -- especially if you have case-sensitive columns in your database. To disable identifier quoting, add the following property to your build.properties (or specify it using -D on commandline): propel.disableIdentifierQuoting=true You can ignore this warning if you understand the issues related to case-sensitivity and Propel's DDL-only implementation of identifier quoting.
