How to download Postgres bytea column as file

Question

Currently, i have a number of files stored in postgres 8.4 as bytea. The file types are .doc, .odt, .pdf, .txt and etc.

May i know how to download all the file store

Answer 1

Best I'm aware, bytea to file needs to be done at the app level.

(9.1 might change this with the filesystem data wrapper contrib. There's also a lo_export function, but it is not applicable here.)
