Ok, thank you, this seems to be the way.
What about the children and grandchildren?
Is there a way to cascade the "pa" query or do I need to query "children" and "grandchildren"
with separate extra queries?
Thanks

Hi,
I would do this way:
After the first step select the required records into another tables with CREATE TABLE patmp AS SELECT * FROM pa WHERE ...
Move these temporary tables to the prod database by dump and restore and transfer the content into the prod tables with INSERT INTO pa SELECT * FROM patmp.
Done.

Hi,
I have 4 tables with 1:n relation:
grandpa -> pa -> child -> grandchild
Now I need to copy an instance of "pa" with his descendants
from my backup (a postgres dump) back to prod.
"grandchild" has a blob column (containing fotos)
Which options do I have?
1) Import the backup dump in a separate postgres instance
2) Do some magic query which created insert statements
3) Run the insert statements on the prod server
What is the best approach, and how does a query look like which
returns nicely formatted insert lines?
Thank you
Marcel
