Disable PostgreSQL Command History

低级别 1自动化postgres

说明

On Linux/UNIX, the PostgreSQL client logs most interactive statements to a history file. The default PostgreSQL history file is named .psql_history in the user's home directory. The PostgreSQL command history should be disabled. Run as root; counts .psql_history files under /home, /root and the postgres home that are not symlinks to /dev/null.

修复方法: 操作指南或基础设施补丁

For each user: rm -f ~<user>/.psql_history, then either add '\set HISTFILE /dev/null' to ~<user>/.psqlrc or ln -s /dev/null ~<user>/.psql_history; optionally set PSQL_HISTORY=/dev/null in /etc/environment.
