[Buildroot] [git commit branch/next] postgresql: init script: wait till server has started

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=e7d515d00e5d36e1260da3768178d2364db1ef90
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Adds "-w" option to init script to wait till the database server
has fully started and accepts connections before continuing.

Prevents other applications that depend on PostgreSQL from
failing to start, if the database server is not ready yet.
Times out after 60 seconds by default.
