This page keeps track of the status of porting PostgreSQL to the OpenVMS platform.
GNV provides a Unix-like environment on OpenVMS. Many Unix utilities are provided by GNV, including bash, awk, sed, tar, gzip, etc. Note that gcc/g++ is a wrapper around the native OpenVMS compiler.
fork()on OpenVMS is like
vfork()on Unix. Note that Win32 also does not support
fork(), so this issue is not new to PostgreSQL. We will need to write a new implementation of
internal_forkexec()(in src/backend/postmaster/postmaster.c) that calls OpenVMS specific routines like
sys$creprc()for detached process.
- Directory separator on OpenVMS is a dot (.), which is different than a / on Unix. Also, ODS-2 disks have more restrictions on filename; ODS-5 disks allow longer filenames, more legal characters within the filenames, and case preserving filenames.
