Description:        pg_restore crashes
Details:

pg_restore ends with ,,Segmentation fault'' or ,,out of memory'' while
trying to restore a large custom-archive-backup (~ 30 GB).

If i choose a table, witch is at the beginning of the backup (according to
pg_restore --list), it works fine.

With smalltable, at the end of the archive, it
ends with a SegFault. So does the same with a big table.
(pg_restore --table=smalltable backup > out.sql)

The Error ,,out of memory'' appears during a restore into the db (using
--dbname=...).

It seems, that pg_restore can't read data behind a limit (2 GB, 8 GB?).

I piped pg_restore through gzip. After a filesize of ~ 7 GB pg_restore
crashes with ,,out of memory''. If the custom archive has the same
compression level, the assumtion for a 8 GB restriction seems to be valid.

This is bad, because you can't use pg_dump & pg_restore for bigger dbs :(
