The TODO item covers my expected behaviour. If you create the database
from scratch, you expect it to have all the alter commands, if you are
restoring into in, you get what is already there.
Also you can pg_restore to a text file if you want those global
parameters out and work with that. So the information is not lost if
it's stored in the dump with the customer format. At the moment the
information is lost at dump time.
I think Richard in correct in the discussion that even though database
information is stored globally, it's not global. If it was, pg_dumpall
-g would dump it.
It's certainly overly complex to get pg_dumpall to give you those
database parameters.
I will leave it there on the basis of the TODO item and previous
discussions.
