Ubuntu :: Finding The PostgreSQL Installed Location?

I'm using ubuntu 10.04 and PostgreSQL 8.4.7. I need to find out where PostgreSQL is located so I can run commands. I successfully installed PostgreSQL without changing any of the defaults. Matthew & Stones' Beginning Databases with PosgreSQL From Novice to Professional, as well as the PostgreSQL documentation, indicates the standard location is /usr/local/pgsql/bin/ but it's not there; it's somewhere else (ps -el | grep post confirms it IS running and psql is able to do du to display the list of users and l to display the list of databases).

But when I tried to create a new user by running /usr/local/pgsql/bin/createuser the command was not found. I tried to locate the installation by running pg_config --bindir but it said pg_config was not installed. I downloaded pg_config and its dependencies and tried to install them with the package installer, but it wouldn't go because something is wrong with the libkrb5-3 and libkrb5support0 packages - they won't install and the package installer just zips through without reporting missing dependencies or anything. The MD5, SHA1, and SHA256 checksums all match, but they just won't install. I then tried the libk5crypto3 package just to make sure something wasn't wrong on my end - it installed fine. So I searched the PostgreSQL FAQ and found out how to get the version without pg_config by doing a SELECT version(); query. here appears to be no corresponding SELECT bindir(); query. A plain ordinary file search for pgsql, postgresql, etc.
