Hi,
I recently stumbled over the following problem, recently because the setup
worked fine for some years, only that when I changed recently to a new
linux distribution (from Suse 10 to the latest Fedora core), things broke.
The set-up is as follows:
I got a postgres data base running on a linux machine (the data base works
ok, it seems, as I can connect to it using the psql ``user interface'' to
interact with it).
I want to connect, however, via emacs, in particular, I used
to use the package
pg.el (Version: 0.10, 2002, it seems)
for it. Now, part of the proper use of it is establishing the
connection with the data base, which is done by:
(setq myconnection (pg:connect "data-base-name" "user-name") )
Now: this connection does no longer work, i.e., I'm refused
access, giving back the following verdict appended below the end of
the article.
Does anybody know how to repair that?
I'm not sure where the problem lies (as said, the set-up worked with the same
version of pg.el and basically the same emacs version before). There seem two possible
sources:
- either emacs/pg does no longer transmit my name properly (I
remember I had problems with encodings some time ago)
- or postgres applies tougher access restrictions on
the new linux distribution, and therefore rejects me
What is strange, however, is that I can access the
running data base as "user-name" using the command-line
tool psql just fine, without being rejected.
Thanks, Martin
