The following bug has been logged online:

Bug reference: 4910
Logged by: Eugen Kraynovych
Email address: y(dot)kraynovych(at)web(dot)de
PostgreSQL version: 8.3.7
Operating system: Gentoo 2.6.14 hardened
Description: pg_restore fails on linux but success on win, buffer
dirty
Details:

Hello,
we have had a servercrash, after that the PG would re-installed. Now i was
restoring the DBs, it was OK bei 3 little DBs, but fails on import of data
bei

curtain tables for other 2 DBs with "pg_restore: [archiver (db)] error
returned by PQputCopyData: server closed the connection unexpectedly". I am
restoring with "pg_restore -d dbname -F c ./database-backup -v -U
username".
See the log message with bad/dirty buffer below.
I have tried to import the DBs on another machine with PG 8.1 and 8.4, with
the same error. The Import succeeded only on Windows XP SP3 (also PG 8.3.7).
The

postgresql.conf on Windows had greater shared_buffers and max_fsm_pages
values, but as i made same values (32MB and 204800) on linux i became the
error

again.
Have somebody probably a hint?
