And the thing is that this creation via DDL is inside our design.
Certain users create some backup tables of the public data in their own
schema (via our app), then do some manipulations on the public data,
then restore to the public or merge with the backups. When done, those
backup tables are dropped. So the DDL is inside the app. And the
question was if dblink is my only option, in the sense of doing this in
a somewhat elegant manner. (and not resort to scripts, etc)
My sense is yes, if you want to encapsulate all of this within the
database/app you will need to use dblink.
postgres_fdw certainly can't do it, nor any other FDW -- the FDW APIs
simply don't cover issuance of DDL. If you don't like dblink, you
could consider writing code within plperlu or plpythonu or another
"untrusted" PL, making use of whatever Postgres client library exists
within that PL's ecosystem to connect to the remote server. It's also
possible that there's some third-party extension that overlaps
dblink's functionality. dblink sure seems like the path of least
resistance, though.
Thank you Tom and Adrian.
