In reading through an old (1987) evaluation of VAX database products
put together by a DEC customer, the following quote caught my eye:
"Dr. Stonebraker at UC Berkeley, the principal designer of INGRES,
has stated that the current version of INGRES is sufficently
'hacked-up' that he will not be using it for the implementation
of POSTGRES."
Can anyone verify this statement? Can we read into this excerpt
that existing INGRES applications may be in jeopardy when the next
generation of RTI software appears?
Just thinking out loud...

1987 is quite awhile ago. I know that the new version of INGRES (6.0 and beyond) has a completely different architecture than the previous versions. The structure has gone to a client -- (multi-)server arch. and all of the associated tools and front ends have been rewritten from QUEL to (portable) SQL. There are other major architectural modifications as well. Perhaps with all of these changes Stonebraker may feel more comfortable continuing to work with RTI's INGRES. --Josh | |||||

Stonebraker may have been talking about not using University Ingres, since he pretty much needs something in the public domain to do Postgres. Anyone who has read the Postgres papers will know that he is doing things so differently that Postgres internals have little to do with Ingres (university or commercial). For example, he is using an Rdb/ELN-like logging/recovery scheme (and claiming he came up with it, ha ha) and not the scheme used by Ingres. This changes most of the internals. | |||||
