For PostgreSQL, you will probably want to use LIB$SPAWN() as a rough equivalent to CreateProcess() on Windows http://www.sysworks.com.au/disk$vaxdocsep002/opsys/vmsos721/5932/5932pro_041.html > Lastly, are we going to support ODS-2 disks??

I hate to pour cold water on this, but why is it worth adding support for a platform that has such marginal usage. -- Bruce Momjian <bruce(a)momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

The implication is that lib$spawn or system() will fail when used this way. http://labs.hoffmanlabs.com/node/794 So we will likely need to use sys$creprc() in internal_forkexec().
