About a year ago, I tried Postgres (Ultrix) and liked it, but I had
certain reservations and questions. I posted the following note and
received a reply, the text is included below.
Have there been any more recent developments regarding my questions in
particular, and regarding Postgres in general?

I am a software developer with DEC, with experience in commercial Ingres
application development (I grew up on version 5 using QUEL). I have recently
downloaded and installed Postgres and have been doing a little experimenting
with it.
I have a few questions for anyone who might know and answer:
- The biggest obstacle I have found for getting good use from Postgres is the
apparent lack of a facility for retrieving status/error information. There
is a reference in the file "c.h" about future plans for a global variable
to contain the status of the last operation (retrieving from the ERROR
relation is mentioned, but I can find no such relation). My question is
this: is there a way that the status/error state for the last operation can
be manually retrieved from some system relation (ala INQUIRE_INGRES)? Could
error text info by subsequently looked up?
- Has anyone written an embedded quel preprocessor ?
- Has anyone done any porting work to OSF ? Specifically OSF running on a DEC
Alpha box ? Would there be any significant difficulties due to 32/64 bit
issues ?
- How about NT ? I gather that the port to NT would by of much
greater difficulty since the sockets and shared memory mechanisms are so
different.
I will look forward to any replies. THank you.

I don't have a good answer for the error-handling question. There aren't
any current plans that I know of to change it.
> - Has anyone written an embedded quel preprocessor ?
libpq is the only application interface that I know of.

We are working on an Alpha port. Yes, there are difficulties with 32/64-bit
issues (though they appear to be of a "massive pain-in-the-rear" nature rather
than really "significant"). In fact, if you have any pull with the DEC
compiler guys, perhaps you could suggest that they provide a command-line
switch that makes "int" 8 bytes for the OSF/1 C compiler..

A Berkeley-written NT port is still very much in the discussion/politics
phase.
