I have quite a few customers that would benefit from the ability to not
have blobs present in dumps.
Great! So how do we proceed to get "--no-blobs" added to pg_dump?
Maybe CommandPrompt and Visena should co-fund development of such an addition,
if it's accepted by -hackers?
We'd be willing to pay for such an addition for the 9.5 branch, as a patch.
Unfortunately this doesn't qualify as a bug fix - it is a new feature and
thus is ineligible for inclusion in official 9.5
David J.
Of course. That's why I mentioned that, if possible, an unofficial patch to
9.5 could be developed, funded partly by Visena (my company). Given that
someone is willing to do this of course.
That probably should look like the patch attached. It applies cleanly on HEAD,
and works AFAICT. If this patch seems interesting enough, I'll add it to the
next commit fest (note for myself, update the ref/pg_dump.sgml documentation
file).
For Andreas' information, it also applies on 9.5, though I didn't check if it
worked afterwards.
+1 for adding it to the commitfest.
It's almost scary how simple this patch is and noone ever got around to
implement it.
Thanks, I'll test it on 9.5 soon.
