More general datafiles ?

P: n/a
Hi ...

I'm sorry if this have been asked many times, but it just seem like a
good approach to me, at least :-)

Is it not possible to design the database files in PG in a way that they
are extentible by nature, at least in one direction (upgrade). This have
been done with taged files (tiff, asn1, amiga) before, and sounds like a
nice way to deal with this problem anyway.

This will make it possible for a new database to insert it new control
data, when it reads the data, and insert it on the flight. The only
thing needed is a possibility to read the old data and insert a
reasenable default for future access.

Is this too primitive or just a to heavy a burden for postmaster ?

Have this been possibility been descused before ?
