Proper handling of connections in subprocesses

Hello,

I'm new to this mailing list, so I don't know if this is a FAQ; but
haven't found an answer via Google or Gmane search.

What is the proper way to handle DBD::Pg database connections in
subprocesses?
I have a master process that has a connection open (and changes the
database). The subprocesses need to access the database as well.

I understand that I have to set the master's connection $dbh
attribute InactiveDestroy to true in the child processes, to
prevent them disconnecting the master connection.

My first question is: Before I do so, can I use $dbh->clone() to
create a new connection for the child process, or should I issue a
new connect() statement for that?
If both works, are there any advantages or disadvantages that I
should be aware of?

My second issue: AFAIU, setting InactiveDestroy is only needed for
subprocesses that exit() or die(). If I have a fork/exec combo, I
don't need that, do I? (Well, maybe for the case that exec won't
succeed and the subprocess dies for that reason?)

Thanks in advance for any answer,

	Joachim

PS: I tried to post via gmane, but that doesn't work as gmane uses 
the [email protected] list. I hope that the email 
doesn't appear twice.
