I´m about to do some web aplications that will save data in a postgreSQL database, but I have one problem: I don´t understand the way postgreSQL saves byte files. I heard about bytea and Large Objects. Are they the same? And how do I insert, say, pdf files in my database? I looked for examples, but didn´t find much (in PHP, obviously). Saludos... :-) -- Porqué usar una base de datos relacional cualquiera, si podés usar PostgreSQL? ----------------------------------------------------------------- Martín Marqués | mmarques@xxxxxxxxxx Programador, Administrador, DBA | Centro de Telematica Universidad Nacional del Litoral -----------------------------------------------------------------
