Why am I getting PostgreSQL-9.2 already exists during an APM install?
This may be seen in Linux variants supporting the APM EM.
Before an APM install, the software performs various checks verifying if PostgreSQL already exists. Always check if the /etc/init.d PostgreSQL startup script file is gone after removing an existing PostgreSQL install. This is typically called postgresql-9.2.
