#!/bin/bash
declare DbHost=<some_host>
declare DB=<some_db>
declare Schemas="select schema_name from information_schema.schemata
where schema_name not like 'pg_%' and schema_name !=
'information_schema';"
for s in $(psql --host=$DbHost --dbname=$DB -AXtc "${Schemas}")

pg_dump --dbname=$DB --schema-only --schema=${s} >
schema_${DbHost}_${DB}_${s}.sql
done
