Manually increase PostgreSQL's table size limit of 32 TB?
Just use a different setting for the block size:


  --with-blocksize=BLOCKSIZE
  
  The default, 8 kilobytes, is suitable for most situations; but other
  values may be useful in special cases. The value must be a power of 2
  between 1 and 32 (kilobytes).


Using 32 kilobytes, your table has a maximum size of 128TB.
