This is version $VERSION.
Common connection options:
-H, --host=NAME hostname(s) to connect to; defaults to none (Unix socket)
-p, --port=NUM port(s) to connect to; defaults to $opt{defaultport}.
-db, --dbname=NAME database name(s) to connect to; defaults to 'postgres' or 'template1'
-u --dbuser=NAME database user(s) to connect as; defaults to '$opt{defaultuser}'
--dbpass=PASS database password(s); use a .pgpass file instead when possible
--dbservice=NAME service name to use inside of pg_service.conf
Connection options can be grouped: --host=a,b --host=c --port=1234 --port=3344
would connect to a-1234, b-1234, and c-3344
Limit options:
-w value, --warning=value the warning threshold, range depends on the action
-c value, --critical=value the critical threshold, range depends on the action
--include=name(s) items to specifically include (e.g. tables), depends on the action
--exclude=name(s) items to specifically exclude (e.g. tables), depends on the action
--includeuser=include objects owned by certain users
--excludeuser=exclude objects owned by certain users
Other options:
--PSQL=FILE location of the psql executable; avoid using if possible
-v, --verbose verbosity level; can be used more than once to increase the level
-h, --help display this help information
-t X, --timeout=X how long in seconds before we timeout. Defaults to 30 seconds.
--symlinks create named symlinks to the main program for each action
Actions:
Which test is determined by the --action option, or by the name of the program
