GiST intarray Memory Allocation

Hi All

Platform: Win32 (XP SP2)

PG: 8.0.3 (default config file)

I have a table with circa 5.5Million rows and an int4[] column containing
about 28 elements each.

When I try to put a CREATE INDEX name ON table USING gist(column);

I get the following :

ERROR: invalid memory alloc request size 2825271912

Any help appreciated or if you need more info just ask.

Thanks

Garrett
