Ensure Data Cluster Initialized Successfully

높음레벨 1자동postgres

설명

First-time installs of a given PostgreSQL major release require the instantiation of the database cluster. A database cluster is a collection of databases that are managed by a single server instance. Checks that data_directory holds an initialized cluster (PG_VERSION) owned by postgres with mode 0700 or 0750; run on the database host. 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.

Initialize the cluster with checksums (PGSETUP_INITDB_OPTIONS="-k" postgresql-18-setup initdb, or initdb -k) and ensure the data directory is owned by postgres with mode 0700 (0750 with group access): chown postgres:postgres <data_directory>; chmod 0700 <data_directory>.
