As a contribution, here is a script to do this for existing databases
(including template1):

=================== begin script enable_pgpl ==============================
#!/bin/sh

# Enable the PL procedural language for PostgreSQL in one or more
# existing databases.
#
# This script should be run by the PostgreSQL superuser

enable_database() {
if ! psql -d $1 -qtc "select count(*) from pg_language where lanname='plpgsql'" >$TMPFIL2 2>&1
then
echo "Cannot connect to $1"
exit 2
fi
if [ `cat $TMPFIL2` -eq 0 ]
then
if ! psql -d $1 <$sqlfile
then
echo "Failed to add PL to $1"
exit 2
fi
echo "PL added to $1"
else
echo "PL is already enabled in $1"
fi

}

# Execution starts here

TMPFILE=`mktemp /tmp/enable_pgpl.XXXXXX`
TMPFIL2=`mktemp /tmp/enable_pgpl.XXXXXX`
trap "rm $TMPFILE $TMPFIL2" EXIT

sqlfile=${PGLIB:=/usr/local/pgsql/lib}/mklang_pl.sql
if [ ! -f $sqlfile ]
then
echo "Cannot find mklang_pl.sql"
exit 2
fi

if [ -z "$1" ]
then
echo "Syntax: $0 --all | database ..."
exit 1
fi

if [ $1 = "--all" ]
then
if ! psql -t -c "select datname from pg_database order by datname" >$TMPFILE
then
echo Cannot select databases
exit 2
fi
for db in `cat $TMPFILE`
do
enable_database $db
done
else
while [ -n "$1" ]
do
db=$1
enable_database $db
shift
done
fi
========================= end ================================
