Uh..."what big tables?" :-)
Have a look back through the archives. I'm mucking about quite
happily with 500 million row tables, without much difficulty.
I've found that my main barrier is disk I/O. If you're doing it on a
little dual-IDE disk system as I am, things just ain't so fast. I'm
hoping that in the next couple of weeks I get the go-ahead to put
together a system with ten or so disks (based around a 3ware Escalade
IDE RAID controller) that will make trillion-row-tables quite practical.

It all depends entirely on the application. Really. Some applications
will work just as well on Postgres as they will on Oracle; others
will be almost impossible with Postgres.
