Thread: question
I am a Comp. Sci. student at Ryerson Polytechnic University in toronto. I am in the midst of a software engineering project that involves the development of a (possibly) relational database on a RedHat 6.2 development environment, we are coding in C. now my question is, how closely related are Postgre and MySQL, and are the necessary PostgreSQL libraries included in RedHat 6.2?
thanks,
Cameron Laird

AFAIK, PostgreSQL and MySQL are from totally different codebases (never shared any code). PostgreSQL is BSD license and MySQL is now GNU GPL. They both implement SQL to varying levels of conformance. PostgreSQL has some object-oriented features, like table inheritance. Try them both and see what you like, but I think you'll find PostgreSQL more interesting. For instance, Postgres can load C functions from shared objects and use them as functions in SQL, user defined aggregates, procedural language call handlers, and to create user defined data types (and possibly other things). The 7.1 beta has implemented some great new features, like write-ahead logging (WAL) and complete support for SQL table joins, among other things. A C project can do a lot with Postgres. RPM packages of PostgreSQL are available at: http://www.postgresql.org/sites.html You'll have to check redhat.com or do an rpm query to see if it should be or is installed on RedHat 6.2. > > thanks, > > Cameron Laird ---------------------------------------- Content-Type: text/html; charset="iso-8859-1"; name="Attachment: 1" Content-Transfer-Encoding: quoted-printable Content-Description: ---------------------------------------- -- -------- Robert B.

I believe redhat does ship Postgres RPMs, but they're PG version
6.5.something, which is pretty old --- ie, fewer features and more bugs
than later versions. You really ought to install PG 7.0.3 (use RPMs
from www.postgresql.org) or if you're feeling bleeding edge, try out the
7.1 beta distribution.

PostgreSQL 7.0 was in beta at the time. PostgreSQL 7.0 was first shipped as 7.0.2, release 17, in RedHat 7.0. RPMS for PostgreSQL 7.0.3 for RedHat 6.2 are available on ftp.postgresql.org, as Tom mentioned, in /pub/binary/v7.0.3/RPMS/RedHat-6.2 The upgrade from 6.5.3 RPM to 7.0.3 RPM is not the easiest in the world -- please be sure to read the README.rpm-dist file in the main postgresql RPM. Also, you will need to read this file to see which packages you want -- for a full client-server install, install postgresql and postgresql-server. Pick and choose the other clients and development RPM's you need from there. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

For the record (with permission of Great Bridge a few months back), I want to thank Great Bridge for helping with the development of the current Official RPMs, including financial assistance (:-)), servers running the distributions in question for building/testing, and top-tier professional feedback (when they say this release has been professionally QA tested, they _mean_ it!) on my little project. Kudos to GreatBridge! -- Lamar Owen WGCR Internet Radio 1 Peter 4:11
I've just moved from Redhat to Mandrake. But do I have to use the Mandrake RPM? Doesn't the standard RPM work on mandrake? What is the difference between these two RPM's? I'd hate to wait for the Mandrake specific RPM for every release. Poul L.

I've been building the Mandrake RPMs, and there is currently a small
problem in the build which I haven't had time to pursue (yet). The
Mandrake distro should be available on the postgresql.org ftp site very
soon after release.

In general, RPMs only work on systems that are the same as the one they were built on, for various degrees of "same". If you're not picking up the RPMs from your distributor or you're sure that the builder used the same version as you have, it's always prudent to rebuild from the source RPM. That should work, unless the package spec makes some unportable assumptions, such as different file system layouts. But that is often only an annoyance, not a real problem. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

While trying to get the FrontPage Extensions installed on a RedHat/Apache system I ran into to different version numbering systems between RedHat and Mandrake. Major pain. One called for perl 5.6.0-xxx and the other perl 5.60-xxx. After several hours of screwing around with it I took a break. Fortunately before I spent any more time on it the client I was going to do it for decided to not run them with Apache. I'm glad to see GreatBridge will be providing RPM's for many distributions. Though I do tend to re-compile from source I've found that those mdk's don't work too good with RHL. Rod --

And I _love_ to get feedback about the nonportable things I do in the spec files (right, Peter ? :-)). I am trying (and Great Bridge helped) to get a fully distribution-independent source RPM working. I am closer than I was -- the same spec file now works on RedHat, Mandrake, Turbo, and (to a lesser extent) Caldera, and soon will work seamlessly on SuSE. It may very well work on others. The hooks are there now for SuSE -- just some fill-in work left to be done. Portability is hard. C programmers have known this for some time -- but the RPM specfile doesn't really lend itself to vast portability. Although, I am learning some real tricks that really help. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

The psql application that shipped with 7.2 was not compiled with ncurses support, so the up-arrow key did not work. Could this be changed with the next release? I recompiled postgres to upgrade to 7.0.3 (and compile perl support) and when I manually compiled it, the up arrow worked in psql. -- ---------------------------------------------------------------- Travis Bauer | CS Grad Student | IU |www.cs.indiana.edu/~trbauer ----------------------------------------------------------------
Ypu can always use the source to build and install it instead of the RPM.
