I doubt it, but then again this why I don't answer Postgres/JSON SO
questions anymore. Trying to apply logic to the contortions people go to
make their life more difficult left me with headaches. At any rate this
is getting off-topic for the the dump/restore issue you have. When you
look at the restored tables in each variation of the restore database do
they look the same as below? If you drop the table in the problem
database and then recreate it using the script below and then populate
it with data does it work?
