Okay... using pg_dump to get the data out of the table is causing
much the same situation. I did a backtrace in gdb, but unfortnately,
I'm running a copy of postgres without debugging symbols, so it may be
of limited use. Here 'tis...
#0 0x80b7590 in WaitIO ()
#1 0x80b6e3c in BufferAlloc ()
#2 0x80b6c6d in ReadBufferWithBufferLock ()
#3 0x80b7390 in ReleaseAndReadBuffer ()
#4 0x8065b90 in heapgettup ()
#5 0x80660a5 in heap_getnext ()
#6 0x8088c61 in SeqNext ()
#7 0x8084480 in ExecScan ()
#8 0x8088ca3 in ExecSeqScan ()
#9 0x80833ce in ExecProcNode ()
#10 0x8082a61 in ExecutePlan ()
#11 0x8082644 in ExecutorRun ()
#12 0x80c1577 in ProcessQueryDesc ()
#13 0x80c15d6 in ProcessQuery ()
#14 0x80c0048 in pg_eval_dest ()
#15 0x80bff56 in pg_eval ()
#16 0x80c0ff1 in PostgresMain ()
#17 0x808f7af in main ()
#18 0x805e1ab in _start ()
I'll see about getting a trace out of a version of postgres with
debugging symbols.
