And for whatever reason, after having worked this morning, it doesn't work anymore after I restarted the computer in
themiddle of the day. I can't believe it. 

When I type in:

    sudo -u _postgres /usr/local/pgsql-9.1/bin/postgres -D /usr/local/pgsql-9.1/data

it spits out:

    LOG:  00000: could not identify current directory: Permission denied
    LOCATION:  find_my_exec, exec.c:126
    FATAL:  XX000: /usr/local/pgsql-9.1/bin/postgres: could not locate my own executable path
    LOCATION:  getInstallationPaths, postmaster.c:1138

I looked around, but couldn't find a plausible explanation for this.
