After upgrading OS X Yosemite Today, start postgesql times the following error:

...
Fatal:could not open Directory "Pg_twophase": No such file or directory
is the server running locally and accepting
Connections on Unix domain socket "/tmp/.s.pgsql.5432"?

It is said that it may be because Yosemite deleted some empty directories of PG, so the solution is simple:

If there are no pg_tblspc,pg_twophase and pg_stat_tmp subdirectories in the/usr/local/var/postgres/directory, you can create these directories directly.

Then you can start the PostgreSQL normally.
