I understand you are confused, as I am too and tried too many things
with no success.
I have postgresql 9.5.3 installed, and the upgrade was from 9.4.8 to 9.5.3.
I can find in /usr/lib64/pgsql/postgresql-9.4 some binaries from
previous versions. Nothing in /opt/ as it can be sometimes indicated.
I have my old database in /db/pgsql/data.old and the new empty
initialized with 9.5 in /db/pgsql/data.old (here versions are given by
PG_VERSION files).

Yes I did many times against a /db/pgsql/data with my 9.4 database (If
I run the command with the 9.5 initialized data folder, I get ERROR:
Cannot upgrade because the database in /db/pgsql/data is of
version 9.5 but it should be 9.4).
The command failed with this error:
--------------------------
*failure*
Consult the last few lines of "pg_upgrade_server.log" for
the probable cause of the failure.
connection to database failed: could not connect to server: No such
file or directory
Is the server running locally and accepting
connections on Unix domain socket "/home/postgres/.s.PGSQL.5432"?
could not connect to old postmaster started with the command:
"/usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl" -w -l
"pg_upgrade_server.log" -D "/db/pgsql/data-old" -o "-p 5432 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/home/postgres'" start
----------------------------
As already mentioned, postgresql put its socket in /run/postgresql.
Btw, both directories (/run/postgresql and /home/postgresql) are
indicated in postgresql.conf:
unix_socket_directories = '/home/postgres,/run/postgresql'
I would like now to try the above command when avoiding this socket story issue.
