Is there a good way to individually list the DDL for all individual data base objects?

Were you aware that pg_restore can restore to STDOUT, and output DDL for only a single named object from a custom dump file?
Yes sir, thank you. That is what the script does.
But that little script seems fragilly-dependent upon the format of the
list file and runs (starts a new process for) pg_restore for every
individual line in the list file. ... which seems like poor practise,
generally. Additionally, I'd like stability in the output file names,
rather than the (likely changing) internal, automatically
numerically-named items.
And, btw, I want not just a single table.
The dependance issue is potentially a problem, but (as I believe) it
looks like the output of pg_restore in a list file is in the correct
order to process dependencies, so I could walk backwards of forwards
through that if changes to one object were dependent on, or caused
cascading effects in other objects.
$ pg_restore —help
…
-f, --file=FILENAME output file name
…
-t, --table=NAME restore named table
…
Such that you could run:
$ pg_restore -f public.mytable.sql -t public.mytable whatever.pgdump
Unfortunately, this does not respect dependencies and you may have issues. The --disable-triggers option can alleviate some of these problems. YMMV.
Hope that helps!
