Mateusz,

At the code sprint we talked about either using tiles small enough to fit
into one postgres page (8K) so perhaps 64x64 for 1band 8bit images or 48x48
for RGB 8bit data.

Alternatively, we might use fairly large tiles to amortize the expensive
BLOB access mechanism in Postgres.

Best regards,
