Karsten, This id good idea but it forces to use Postgres protocol for downloading. This protocol has some timeouts which are too small for large file download. Postgres protocol has also a lot of overhead added to downloadable data. It also requires that whole downloadable file must fit into memory. I used ODBC. I tried this but was forced to store big files in 1 MB chunks in bytea fields and create file from downloaded blocks So I'm looking a more efficient protocols to download backup file. Or should I really write code which divides backup file to 1 MB chunks and stores them in bytea field ? Andrus.
