My 1004 Post

That would probably be 4294967295. You've a long way to go.

God, I remember the days of trying to get the highest postcount possible...

That would probably be 4294967295. You've a long way to go.

That doesn't make any sense.

4294967295 what? Clarify please.

(2^32) - 1 = 4,294,967,295.

My guess is that the postcount is saved as an integer, which in SQL is stored in 32 bits, so the highest number of posts he can get has to be (2^32) - 1 because there are 2^32 values, but one of them is zero, hence the - 1.
