起動しようとするたびにpostgresql失敗します。私はKali NetHunterを実行しています。
これは私の端末出力です

答え1
postgresqlエラー状態など、十分に大きな共有メモリセグメントを作成できないため起動しません。
could not create shared memory segment: Function not implemented
Failed system call was shmget
この問題を解決するには、次の手順を実行します。
sudo sysctl -w kernel.shmmax=134217728
再起動後に恒久的に設定するには、/etc/sysctl.conf以下を編集して追加しますkernel.shmmax = 134217728。
sudo vi /etc/sysctl.conf
kernel.shmmax = 134217728
更新された回答：
OPヘルプによるデバッグ：
sudo sysctl -w kernel.shmmax=134217728 sysctl: cannot stat /proc/sys/kernel/shmmax: No such file or directory
Kali NetHunterがAndroidデバイスで利用可能であることを考慮すると、最も正確で明確な答えは、shmemこのカーネルバージョンではサポートがコンパイルされないことです。
これはまたshmem。Apache
残念ながら、Androidに似たデバイスでpostgresqlデータベースを実行することはあまり意味がありません。
それにもかかわらず、1つの可能性は、shmemをサポートする他のカーネルパッケージ（存在する場合）を見つけるか、極端な場合はカーネルをクロスコンパイルすることです。もちろん、デバイスのディスクやメモリが不足している場合は、このパスを考慮しないでください。
