Case-sensitive behavior cannot be achieved for PostgresSQL databases. PostgreSQL databases internally convert all names to lower case, which makes the following workarounds necessary:
In the CMP 2.1 runtime, PostgreSQL table and column names are not quoted, which makes these names case insensitive.
Before running the capture-schema command on a PostgreSQL database, make sure table and column names are lower case in the sun-cmp-mappings.xml file.
