Installing PostgreSQL on Mac OS X 10.6.4 Snow LeopardEdit

Created , updated

I found a bug in Rails 3.0.0.rc, specifically in Action Dispatch, and in order to submit a failing test case I need to install PostgreSQL, unfortunately. (The tests won’t run without doing bundle install first, and bundle install wants the "pg" gem to be on the system, which in turn depends on a working PostgreSQL install and headers.)

$ wget http://wwwmaster.postgresql.org/redir/149/h/source/v8.4.4/postgresql-8.4.4.tar.bz2
$ wget http://wwwmaster.postgresql.org/redir/149/h/source/v8.4.4/postgresql-8.4.4.tar.bz2.md5
$ cat postgresql-8.4.4.tar.bz2.md5
$ md5 postgresql-8.4.4.tar.bz2
$ tar xjvf postgresql-8.4.4.tar.bz2
$ cd postgresql-8.4.4
$ ./configure
$ make
$ sudo make install
$ OLDPATH=$PATH
$ export PATH=/usr/local/pgsql/bin:$PATH
$ sudo gem install pg
$ export PATH=$OLDPATH
