Yes. It is set when Postgres starts up, and cannot be changed without a restart. The value
can be hard-coded in your postgresql.conf file, but usually defaults to the PGDATA
environment variable, or the -D option to the 'postgres' program.

Yes. But I would be careful, it looks like you have may have two active clusters. I'd
document everything clearly before proceeding: use "show port" and
"show unix_socket_directories" to learn why you can connect to both clusters at the
same time, if that is the case.
