I have installed a postgres in a SunOS 5.8 sparc SUNW,Sun-Blade-1000. By
default when i create a table of the form (int4, int4) which is the
average tuple size except of the theoretical 4+4 =8 bytes of data
size, including all the object identifiers that I suppose that are
included? Namely which default object identifiers are included in each
tuple and consequently to each table, database storage. Thank you!

Re: Tuple, table, database object identifiers size

It's in the docs somewhere but I think it's about 40 bytes.

It is in the FAQ.
