Non-interactive PostgreSQL query tool.
By default, it outputs JSON which means that you can process and view the results with tools like jq or catj.
npm install -g pgcmd
pgcmd -h localhost \
-u postgres \
-p p@ssw0rd \
-d postgres \
'select * from pg_database where datname = $1' \
-m template0
If no script is specified, pgcmd reads from the standard input:
echo 'select * from pg_database where datname = $1' | pgcmd -m template0
Output:
[
{
"datname": "template0",
"datdba": 10,
"encoding": 6,
"datcollate": "en_US.utf8",
"datctype": "en_US.utf8",
"datistemplate": true,
"datallowconn": false,
"datconnlimit": -1,
"datlastsysoid": 13066,
"datfrozenxid": "562",
"datminmxid": "1",
"dattablespace": 1663,
"datacl": "{=c/postgres,postgres=CTc/postgres}"
}
]
It can also output CSV:
pgcmd 'select * from pg_database' --csv
Output:
datname,datdba,encoding,datcollate,datctype,datistemplate,datallowconn,datconnlimit,datlastsysoid,datfrozenxid,datminmxid,dattablespace,datacl
