RE: pg_dump & blobs - editable dump?

Which is why having them on stdout is still a nice option to have. You can
pipe the lot through your favourite compressor (gzip, bzip2 etc) and
straight on to tape, or whatever.

I don't know why you would want them as separate files - just think what
would happen to directory search times!!

How about this as an idea:
    * Option to dump sql to stdout and blobs to a designated file
    * option to dump sql & blobs to stdout
    * option to dump just sql to stdout
    * option to dump just blobs to stdout

That way (depending on the database design), you could handle the sql &
blobs separately but still have everything backed up.

PS: Backups is formost on my mind at the moment - had an NT one blow up in
my face on Monday and it wasn't nice :-(

For the human readable version, the request was to make it editable and
sendable to psql. As a result the BLOBs need to be in their binary format
OR psql needs to support BLOB import from stdin. As a first pass I was
hoping for the simple 'dump them into files' solution.

What I am confused by is what people actually want to do with a load of
BLOBs sitting in a directory; if there are specific needs, then I'd also
like to cater for them in the custom file formats.
