Bingo - maxDATA of 0x00000000. Ken's posting was correct. You have
1x256MB segment of memory available per process.
If you watch your server process while this is happening, it will be
hitting 256MB in size.
Upping this limit is probably the way to go. You can use the ldedit
command to up this limit for your binaries, or specify it when you build
Postgres. See the file docs/FAQ_AIX with the PG source for details.
