Hello,
I've been using libpqxx to access a Postgres database for the last few

These allow database tables and rows
Hi all,
well, the most of the programming itself is done, what's currently missing is
1) Some fine tuning on the layout
2) Adding the static pages
3) Translating the pages, news, events etc. into german and maybe some other languages
if we find someone to translate it
4) Creating something that
I am running PostgreSQL 7.3.1 on i686-pc-linux-gnu, compiled by GCC 2.96

I think it is part of the incentive for corporations to contribute - not
just an impressive list for PHB. It's nice to get the recognition for
their time/money contributions and a good way for the PGDG to show their
appreciation.

It's really useful. I don't think there is any major risk in adding the
delay patch into a minor revision given the small amount of code change.

I thought the whole problem here is that OIDs are unsigned ints, hence

Exactly. That's why you need to handle T_Float too. See the int8
example, which has just the same problem.

I don't think so, unless you are proposing something very odd in the

context.
