Take the whole directory - there are indexes as well. And large tables

You may try the following shell script to determine the size of all
databases:
#!/bin/bash

# Shell script to determine disk usage of PostgreSQL databases.

PGDATADIR=/data/pgsql/74
PGPORT=5432
PSQLBIN=/opt/pgsql-7.4.3/bin/psql
PGOPTS="-U postgres"
echo "PostgreSQL 7.4.3 database sizes"
$PSQLBIN $PGOPTS -p $PGPORT -t -F " " -A template1 -c 'select oid,datname from pg_database' | \
while read oid dbname ; do
[ "$dbname" != "template1" ] || continue
[ "$dbname" != "template0" ] || continue
size="`du -sh $PGDATADIR/base/$oid | cut -f 1`"
while [ ${#dbname} -lt 16 ] ; do dbname="$dbname " ; done
printf "$dbname\t%6s\n" $size
done
