mount /dev/shm manually

eg. mount -t tmpfs tmpfs /data/ubuntu/dev/shm

Does not seem to work

I also notice this mount already in the bootlinux_init. May be it's another issue

The full error (debian 11):

This user must also own the server process.

After some investigations, I'm been able to get postgres running.
First compile android-shmem from source inside chroot eviroment (or cross compile on PC, as long as it is same architecture with your phone cpu).

You'll need to make a modification to this part, remove the if statement(I have no idea what will it affected).

Then move the .so file to /lib (inside chroot), mine is /lib/libandroid-shmem.so
Now before do any thing with postgres server, you it to custom LD_PRELOAD like this

env LD_PRELOAD="/lib/libandroid-shmem.so" pg_ctl start
