Both the database and the platform are seriously obsolete :-(

It appears that you're working with a pg_restore binary that doesn't
support access to files larger than 2G.  This is mostly an issue of what
the platform's libc can handle; and on many platforms it depends on
build or link options.  I no longer recall whether RH 7.3 supported
largefile access at all, let alone what build-time pushups were needed
to make it happen if it could happen.

My recommendation would be to get hold of a current PG version, dump
using the current version's pg_dump, then install and reload into the
current version.
