Passing a PGconn * between two processes on Unix like systems - Mailing list pgsql-general

I two Unix/ process related questions:

Is there a documented way to pass around an (opened) PGconn * structure
between two processes on Unix?

When a process forks() and both the parent and child process continue to
use a previously opened PGconn * structure, is that behaviour defined?

Thanks,
