Try:
df -k | sed "s/^/`hostname` /"
Get the quoting right. This uses double quotes and backquotes. It does not use single quotes.

dropdb
DROPDB(1) PostgreSQL Client Applications DROPDB(1)
NAME
dropdb - remove a PostgreSQL database
SYNOPSIS
dropdb [ options... ] dbname
DESCRIPTION
dropdb destroys an existing PostgreSQL database. The user who executes this command must be a database superuser or the owner of the data-
base.
dropdb is a shell script wrapper around the SQL command DROP DATABASE [drop_database(7)] via the PostgreSQL interactive terminal psql(1).
Thus, there is nothing special about dropping databases via this or other methods. This means that the psql must be found by the script and
that a database server is running at the targeted host. Also, any default settings and environment variables available to psql and the
libpq front-end library do apply.
OPTIONS
dropdb accepts the following command-line arguments:
dbname Specifies the name of the database to be removed. The database must be one of the existing PostgreSQL databases in this installa-
tion.
-e
--echo Echo the queries that dropdb generates and sends to the server.
-i
--interactive
Issues a verification prompt before doing anything destructive.
-q
--quiet
Do not display a response.
createdb also accepts the following command-line arguments for connection parameters:
-h host
--host host
Specifies the host name of the machine on which the server is running. If host begins with a slash, it is used as the directory for
the Unix domain socket.
-p port
--port port
Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the server is listening for connections.
-U username
--username username
User name to connect as
-W
--password
Force password prompt.
DIAGNOSTICS
DROP DATABASE
The database was successfully removed.
dropdb: Database removal failed.
Something didn't work out.
If there is an error condition, the backend error message will be displayed. See DROP DATABASE [drop_database(7)] and psql(1) for possi-
bilities.
ENVIRONMENT
PGHOST
PGPORT
PGUSER Default connection parameters
EXAMPLES
To destroy the database demo on the default database server:
$ dropdb demo
DROP DATABASE
To destroy the database demo using the server on host eden, port 5000, with verification and a peek at the underlying query:
$ dropdb -p 5000 -h eden -i -e demo
Database "demo" will be permanently deleted.
Are you sure? (y/n) y
DROP DATABASE "demo"
