[pgadmin-support] Calling a Postgres utility in pgpsql function

[Vish Phaneendra]

Hi,

Is it possible to call a postgres utility from pgpsql function? I'm  
trying to get the table definition using the pgpsql function.

CREATE FUNCTION table_definition(text) RETURNS text AS $$
pg_dump -st $1
$$ LANGUAGE plpgsql;

Rgds,
Vish
