You do realize that timestamps are floating point seconds relative to AD
2000, and so the accuracy decreases as you get further away from current
time?

I don't believe that Postgres will associate any timezone at all with
timestamps outside the range of the underlying OS' timezone database.
I get just
regression=# select '1850-Jan-01 03:23:49'::timestamp;
?column?
---------------------
1850-01-01 03:23:49
(1 row)
I'd say the problem here is on the Java side: something on the client
side is inappropriately attaching a timezone to a value that should not
have one. Possibly you should take this up on pgsql-jdbc; or perhaps
it's a problem with the Java datetime datatypes you are using.
