Is our maximum table size limited by the maximum block number?
With our block number maximum of:
#define MaxBlockNumber ((BlockNumber) 0xFFFFFFFE)
0xFFFFFFFE = 4294967294
would the max table size really be (4GB * 8k) or 32 TB, not 16TB, as
listed in the FAQ:
4.5) What is the maximum size for a row, a table, and a database?
...
Maximum size for a table? 16 TB
Is the 16TB number a hold-over from when we weren't sure block number
was unsigned, though now we are pretty sure it is handled as unsigned
consistenly?
