I had access to the HP testdrive before they closed it down (the Unix
servers were down in Sept 08, but the VMS cluster was running till Jan
2010). They blocked all outbound internet access to the testdrive
servers -- only telnet and ftp were allowed.

Count me in for the OpenVMS porting effort (but I guess I will apply
for an account seperately as I might port other things to OpenVMS in
the future). I believe the porting effort is larger than a new Unix
port but smaller than the Windows port, as most of the Unix and POSIX
functions and system calls are supported on OpenVMS.

MySQL has around 10 functions changed or written specifically for
OpenVMS, most of those are related to utime(), $UMASK & $UMASKDIR,
open(), and Unix pathnames. (I think utime() support was added a few
years ago to OpenVMS 7.3 & 8.0 -- so may be the code was added to
MySQL for earlier VMS versions.)

PostgreSQL uses fork(), which is not supported on OpenVMS. However,
the techniques used by the WIN32 version of internal_forkexec() in
src/backend/postmaster/postmaster.c give the VMS version a good
starting point.

Lastly, are we going to support ODS-2 disks?? And are we going to
require GNV installed for building and running PostgreSQL on OpenVMS??
