Per Tom's comment, what are the encodings?
Just sent reply to his mail with the encodings
Also I would point out that the problem occurs on the machine you are dumping/restoring backwards 9.6 --> 9.4. Not sure if that is relevant or not, but worth looking at.
How is the dump/restore done(plain text, custom format, etc) and what are the command strings?
I pasted 2 days at pastebin
(with date marking added)
Also what versions of pg_dump/pg_restore are you using on the dump and restore sides for the various Postgres versions?
Hmm, now that is tricky,
The prod has - as I briefly mentioned - been on the AWS
So I used its pg_dump. But I don’t recall version
In my notes I can see that we started with an ubuntu 12.04 image
But - I always use the pg_dump that belongs to the source database
And psql that belongs to the target database
So insert is
bnl@ibm2:~/db$ psql
Tidtagning är på.
AUTOCOMMIT off
psql (9.6.15, server 9.4.15)
Skriv "help" för hjälp.
While pg_dump may have varied through the years
The dump at pastebin gave me no clue of version that created it
Lately (the lsat 2 years or so) it has ben the pg_dump on the pi
bnl@pibetbot:~ $ pg_dump --version
pg_dump (PostgreSQL) 9.6.10
But not for that data sep/oct 2016
Yes really, otherwise you would not be seeing a difference. Sorry, pet peeve of mine, when people say these two things are not doing the same thing but then say they are the same thing.
I mean, the pg_dump does copy-commands.
It also does a certain amount of setup at the beginning of the file.
I stand corrected
