PostgreSQL package for nanos

[rrs45]

Given that postgres is multi-process system, is it possible to run it on Nanos? There is a way to run it in single-user mode, will this allow it run on Nanos?

[francescolavra]

Unfortunately not, PostgreSQL is heavily dependent on fork()ing child processes to process DB requests, and fork() is not allowed in Nanos. It's also dependent on other things that are used in multi-process applications, such as shared memory segments and SIGCHLD signals, so it cannot be easily patched to make it runnable with a unikernel.
