Please provide a step-by-step answer on how to build a basic Entity-Relationship Diagram (ERD) using the admin tool that comes with
postgres (pgAdmin) with the the database designer that comes with postgres.
Note that the general question on what is the best way to generate a diagram from postgres, is addressed in this softwarerecs.stackexchange question
Update
Sadly, the database designer is not released with the main release of pgAdmin after all. (At least the case for version 1.16 through 1.22.)
See discussion here and here and finally:
You need to use --enable-databasedesigner with ./configure to enable
it. By default, it's disabled.
There are too many bugs and rough edges and not enough people interested to work on it.
pgAdmin had a GSoC project in 2011, in the course of which Luis Ochoa designed the new database designer - which can also reverse engineer ER diagrams from existing dbs. Unfortunately it wasn't ready for release with pgAdmin 1.14 (the current version). But it's in the repository for version 1.16 that will probably accompany the release of PostgreSQL 9.2.
See a video here.

Blog post announcing it.
There are still some rough edges, but Luis Ochoa recently announced he is working on it.
If you are running Linux, you could use pgDesigner: http://sourceforge.net/projects/pgdesigner/

Postgres is great, but it misses many quality of life features. For example, you can't perform an UPSERT without explicitly stating all of your columns. You can code some dynamic SQL to solve this, but wouldn't it be better to install someone else's code?
In almost all programming languages we have repositories of useful, community driven packages. Think pypi + pip in Python or npm in JS. Is there something similar for PostgreSQL, or at least some place to search for snippets?
I've tried to search on Google, but it is really hard to find anything, as most searches give you tutorials or documentation pages.
there are , you can add custom feature using extension in postgresql
and there are tens of open source extensions on github apart from official extensions available for postgresql

Does anyone know of a free build server service to coincide with scm/forum/issue tracking services such as sourceforge/googlecode?
Obviously hudson/jenkins service would be my first preference related to primarily java/maven2, but anything would be nice!
Thanks!
Cloudbees has an offering for FOSS projects.
Another one (especially for public Github repos): http://travis-ci.org/
Researching the same thing currently, I stumbled over jenkinshosting.com (reported as suspicious site, Aug2012)- Jenkins build server, free for FOSS. Haven't tried it yet, though.
Atlassian offers licensed and on-demand products to open-source projects. Bamboo may be included.
https://www.atlassian.com/software/views/open-source-license-request
A TeamCity based server farm is available for open source projects through http://teamcity.codebetter.com/. Read the announcement.
Another option for OSS is http://www.appveyor.com/, which is including support for Windows 8.1 store apps.
Jenkinshosting.com use to offer free open source hosting. It's worth checking out to see if it's still continued.

Is there any software for viewing UML-like diagrams of postgreSQL DB schemas for the Mac? Here's an example of what I would like to see.
(source: google.com)
Cheap's good, free's better.
A similar question was asked here, but the software pointed to here appears not to be available for the Mac, and is no longer being supported anyway.
Some days ago I had the same question. I found several, but the one that I'm using is DbVisualizer. It is multi-platform, free, and easy to install. It also has a paid version, but the free one is enough for visualization purposes. It supports PostgreSQL, MySQL, Informix, Oracle, Microsoft SQL Server, and many other DBMS'.
Here is the download link
DbWrench is not free (but not expensive either) and quite good: http://www.dbwrench.com/
PowerArchitect Community edition is free, but the really interesting features seem to go into the enterprise edition: http://www.sqlpower.ca/page/architect
Both are Java based and work on the Mac
Aqua Data Studio offers an ER diagram generator and ER modeler but it's pricey now.
Free licenses for qualified open source developers; reduced licenses for qualified academic users.
The accepted answer's link doesn't work any more.
Here is an acceptable tool that's free and produces graphic diagrams: http://www.dbvis.com/

I use PostegresQL 9. Is there a free tool to derive UML diagrams from my databases?
Thanks
For creating ER diagrams by db reflection, I use:
DbVisualizer
http://www.dbvis.com/
It's free.
There's also postgresql_autodoc which can create GraphViz or Dia output. The diagrams will likely require further tweaking, though.
There's a free tool called Dia and a plugin called PostDia. They would do it for you.
Plus:
it generates postegres sql scheme files too
Both are free.
Requirements for PostDia: python and psycopg2, to install the second one:
pip install psycopg2
Found DBeaver here:
https://softwarerecs.stackexchange.com/questions/34552/generate-database-table-diagrams-from-a-postgresql-database
Tested it with postgres. Works great.
https://dbeaver.io/download/
free, multi-platform universal SQL client. Supports all popular databases: MySQL, PostgreSQL, MariaDB, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Derby, etc.
I think ArgoUML can do it. Let us know
EDIT: Actually ArgoUML does not seem to reverse engineer, take a look at http://databasetouml.org/roadmap.php or search more for extensions to Eclipse
There was Azzurri Clay plugin for Eclipse with db reverse engineering support (v 1.4 as I remember). But in v 2.0 the company developing this plugin moved the reverse engineering feature to the licensed version of the plugin. There were some manuals in the internet how to downgrade from v2 to v1.
EclipseUML can do the job but it is not free. What is cool with this tool is that they have a database profile therefore you can see full database information into your class diagram.

Very simple question (I hope), does there exist a tool similar to phpMyAdmin when working with a MySQL DB but for PostgreSQL databases?
The reason I'm not just googling for a solution is that I am not as familiar with PostgreSQL as I am with MySQL and I was hoping that the SO community would be able to provide a tool that you have experience working with.
Thank you in advance for any responses. :)
There is a similar tool, phppgadmin. The layout is bit different from phpmyadmin but I've used it on a few of my web servers and the interface works very nicely and it's just as useful.
If you prefer a GUI app, this is really good:
http://www.pgadmin.org/features.php
The RazorSQL SQL GUI Tool supports PostgreSQL and MySQL.
PgManager 3 is a good one to administrative tasks (www.pgadmin.org) [not so sweet for development tasks as pgplsql dev). But you even can handle slony replication with this tool.
There is a commercial one, SQL Management Studio for PostgreSQL, it is a really good one, I was using it since a lot of time and it really shines in development and administrative tasks (http://sqlmanager.net/en/products).
Navicat for PostgreSQL is an easy one to use, simple administrative tool very similar to the MySQL one. (pgsql.navicat.com) [commercial]
I remember there was a few one, but right now I can only remember those three.
Hope it helps to you!
The Tadpole DB Hub supoort PostgreSQL and Mysql, SQLite, MSSQL, Oracle, Mongodb... etc..
