You can use a stored procedure with this pl
http://plsh.projects.postgresql.org/ , like this:
CREATE FUNCTION dump_db(text, text) RETURNS text AS '
#!/bin/sh
pg_dump $1 > $2
' LANGUAGE plsh;
Note that you must CREATE LANGUAGE first, $1 is db_name, $2 is file
name and check for write permissions of $2. Be careful and check your
security because any shell script will run as postgres user. Don't
know if it works with 9.x+ versions of postgres.
