TMA-PGSQL-PASSWORD-ENCRYPTION
Ensure 'password_encryption' is set to 'scram-sha-256'
보통레벨 1자동postgres
설명
New passwords should be stored as SCRAM-SHA-256 verifiers rather than MD5 hashes (MD5 support is deprecated in PostgreSQL 18). Not a separate CIS PostgreSQL 18 recommendation (see the 5.4 default-value notes). Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.
