I just compiled pgsql version 7.3.2 in a redhat 7.3 workstation and I
get this error when I run psql:
psql: /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by
psql)
I have to update glibc? How? No rpms are avaliable, how the configure
script haven't detected this problem?

No, they support the syntax:

syntax, because they were using informix. There is also a rather

While I don't see the syntax of:
update table set (col...) = ( val...)
as valuable compared to separate col=val assignments, I do see a value
in allowing subqueries in such assignments:

Without it, you have to do separate subquery

Hi,
I've been looking at the dependency API and I notice that there is a

Is there any other way of doing this other

This is certainly the case here. I think IBM is deprecating informix,

seriously considering postgres as an alternative.
Do you have any evidence that they are evaluating it?

Well, yes it will if you look at the big picture. In the past we've
