Hanging with pg_restore and large objects

Hi all.

  I've  encountered  the  following  problem:  pg_restore  hangs while
restoring LOBs. The situation is as follows:
  1) TARed dump, created by pg_dump 8.3.6
  2) pg_restore from Postgresql 9.1.1
  3) pg_restore  restores schema and most of LOBs, but hangs on one of
     them  (the  same  LOB every time). 'ps' shows 'R+' state for
     pg_restore, and GDB (attached to pg_restore) gives the following:

(gdb) bt
#0  0x0000003ec6ec6750 in __read_nocancel () from /lib64/libc.so.6

#12 0x00007fff51ae6188 in ?? ()
#13 0x0000000000000000 in ?? ()

  Does anyone know, what can be wrong?
