bash-4.1$ cat givepid.sh
HOSTNAME=`hostname`
PSQL="/opt/PostgreSQL/9.3/bin/psql"
PORT=5432
HOST="localhost"
DB="template1"
echo "Enter the value of PID";
read pid
$PSQL -d $DB -U $USER -p $PORT <<EOF
\pset format wrapped
SELECT now() - query_start as "runtime",state,query from pg_stat_activity WHERE pid= $pid;
EOF
exit 0;

Enter the value of PID
32696
Output format is wrapped.
    runtime     | state  |                                                                       query
