Another history question

I know that postgres was a project directed by Michael Stonebraker in
Berkeley (1986-1994) and that soon Jolly Chen and Andrew Yu did
postgres95.

I understand that the main change in postgres95 was to implement SQL
instead of POSTQUEL. Then after the appearance of postgres95
postgreSQL 6.0 arises. And what came later it is well-known history.

My question is if the architecture of postgreSQL were inherited of
postgres original project or postgreSQL were developed completely with
a new concept. Thanks in advance.

There hasn't been any fundamental rearchitecting since Berkeley days.
For instance, look at Postgres 4.2 --- those sources are available on
the net, and if you compare them to current CVS you'll find plenty
that's recognizably the same code.

Thanks for the explanation. Then, Can I say that PostgreSQL and
Informix are cousins?
