Among other uses, it enables easy post-processing of psql output using `jq`: $ psql -lJ | jq [ { "Name": "myon", "Owner": "myon", "Encoding": "UTF8", "Locale Provider": "libc", "Collate": "de_DE.utf8", "Ctype": "de_DE.utf8", "ICU Locale": null, "ICU Rules": null, "Access privileges": null }, ... ] Christoph
