Homebrew postgres broken

Question

I installed Postgresql 9.4.0 installed on my Mac (10.10.1/Yosemite) using homebrew. It does not work.

I have created the softlink to /usr/local/opt/postgresql/homebr

Answer 1

After trying to install postgresql with Homebrew, I got this:

Warning: postgresql-9.5.2 already installed, it's just not linked

So I tried:

brew link postgresql

And got this error:

Linking /usr/local/Cellar/postgresql/9.5.2... 
Error: Could not symlink share/man/man3/SPI_connect.3
/usr/local/share/man/man3 is not writable.

It seemed to be a write permission matter, so I did:

sudo chown -R `whoami` /usr/local/share/man/

It did the trick because, then I was able to do (without error):

brew link postgresql
