an atypical pg_restore?

Hi:

   I'm in the midst of upgrading from 8.1.5
to 8.2.1 usng pg_dumpall and pg_restore.
My database is about 95 G in size and contains
several very large tables having indexed columns of
the geometry datatype (PostGis). Otherwise,
my database is pretty conventional. My problem:
the restore is taking forever.  It's now day
12 and about 86 G has been restored.

   Here are some details:

   1) Hardware:

SunOS 5.9 Generic_117171-07 sun4u sparc
SUNW,Sun-Fire-V240

System Configuration: Sun Microsystems  sun4u Sun Fire V240
System clock frequency: 167 MHZ
Memory size: 2GB

CPU states: 95.5% idle,  2.4% user,  2.1% kernel,  0.0% iowait,  0.0% swap
Memory: 2048M real, 1403M free, 118M swap in use, 3384M swap free

    PID USERNAME THR PRI NICE  SIZE   RES STATE    TIME    CPU COMMAND
  29520 postgres   1  60    0   59M   44M sleep  913:46  2.26% postgres

etc, etc.

   2) Dump/restoration commands: pg_dumpall (no options) and
pg_restore (no options).

   3) Restoration progress as of today:

day    gigabytes restored (cumulative)
---     -------------------------------

7    52
8    57
9    83
10    84
11    85
12    86

   In the beginning, I was getting about
9 G restored daily.  But on day 9 and thereafter,
the rate slowed to 1 G.  On day 9, the
restoration of the indices began.  My biggest
indices are those covering the geometry columns.

My question: is my experience here atypical?

Thanks!
