Ish: Failed system call shmget while running initdb (Postgres cant be started)

[AlZeck]

This is the complete verbose of running initdb

$ initdb -D /var/lib/postgres/data

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locales
COLLATE: C
CTYPE: C.UTF-8
MESSAGES: C
MONETARY: C
NUMERIC: C
TIME: C
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

Any progress on getting postgres working?

No, but I'm open to contributions

Would love to contribute but don’t know C or alpine or linux internals. If I can help or learn to help I am willing. Am an ex full stack web developer and am learning python. I’ve also done some basic Objective-C and Swift.
