[GENERAL] Cause of ERROR: could not open relation 1663/856689/856777: Invalid argument?

[Wyatt Tellis]

Hi,

I'm running 8.1.4 on W2K3 R2. I occasionally get errors of the type:
ERROR: could not open relation 1663/856689/856777: Invalid argument

where the last two numbers change. This only seems to happen during 
inserts into the largest table in the database (>500,000 rows). What 
does this error message mean?


Thanks.
