I removed subtests.

For example, with most packages and functions in Perl that run a command, you can pass the command as a string or as a list (or array reference). The latter is preferred because it avoids issues with quoting, word splitting, spaces, etc. In IPC::Run, I can use the "run" function in the latter way, but I cannot use the "run_forked" function like that, and I need that one to get the exit code of a command. It's possible to work around that, but I'm getting the feeling that this is not very well designed. Also, IPC::Cmd is a wrapper module, and it passes the hard work down to other modules, depending on what's available. I think that sounds like a portability problem waiting to happen. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
