Ensure the log file permissions are set correctly

MediaNivel 1Automatizadapostgres

Descripción

The log_file_mode setting determines the file permissions for log files when logging_collector is enabled. The parameter value is expected to be a numeric mode specification in the form accepted by the chmod and umask system calls. Expects 0600, the benchmark value and default. 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.
