Theoretical limit. The row slot enumerator is a 32-bit unsigned integer.
Deleted rows, as well as uncommiitted and obsolete record versions still
occupy slots. I believe Nickolay bumped that up to a higher power in Fb 2,
though I have a vague memory that it's not a 64-bit integer, maybe
2^40. (Which reminds me, I don't think that got into the Fb 2 alpha
release notes...) Blobs that are stored on data pages play a part in
lowering the theoretical limit, too.
