Hi,
Fedora packages have an executable (not sure about its name, but check
a
package called postgresql-upgrade or so). That will help you to finish
the
upgrade process.

Hello
Yes, the package is called postgresql-upgrade, and you can read
detailed
instructions in /usr/share/doc/postgresql
In Fedora 22 (the machine i can check now) the document is called
README.rpm-dist in that directory
Hope helps you
I effectively found the postgresql-update tool. But when running it, I
get an error:
# postgresql-setup --upgrade
* Upgrading database.
ERROR: pg_upgrade tool failed
ERROR: Upgrade failed.

My data dir is in fact /db/pgsql/data. I do not know why it is looking
for data-old.
I will investigate this way.
It took me some time to figure out the correct way for Fedora to
upgrade pgsql. Here is the command I am supposed to run as postgres
user, with postgresql.service stopped:
$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d
/db/pgsql/data.old -D /db/pgsql/data
with data a new DB initialized with postgresql 9.5, data.old my
original DB, postgresql-9.4/bin old cluster executable.
NOTE: I didn't put my original config files pg_hba.conf, pg_ident.conf
and postgresql.conf in the new data directory. I left everything
untouched after the init command. Is it correct ?
The above command returns an error:
-----------------------------------------------------------------------
*failure*
Consult the last few lines of "pg_upgrade_server.log" for
the probable cause of the failure.

My postgresql service is in fact started with its socket in
/run/postgresql directory, as indicated in my postgresql.conf. Now,
when running pg_upgrade, where is the socket ? I guess it shall be in
<< unix_socket_directories='/db/pgsql' >> as indicated in the log file
above? But it isn't apparently as postgresql can find the socket. How
can I change this behavior? How can I tell pg_upgrade to place the
socket in /db/pgsql ?
Thank you for help. This issue is getting me crazy and my mail server is
broken.
UPDATE
Running the following command (it indicates where to find the socket):
$ /usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl -w -l
"pg_upgrade_server.log" -D "/db/pgsql/data.old" -o "-p 50432 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/run/postgresql'" start >>
"pg_upgrade_server.log"
leave me this time with another error, in fact the original one:
% cat pg_upgrade_server.log
waiting for server to start....FATAL: 22023: database files are

Actually it is the opposite of your original message:
"postgres(at)thetradinghall ➤➤ systemd/system %
/usr/libexec/postgresql-ctl start -D /db/pgsql/data -s -w -t 270
FATAL: 22023: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.4,
which is not compatible with this version 9.5.3.
So aside this socket issue, it seems I am back again to the
initialization issue. Is there something wrong in the command I use ?
$ pg_upgrade -b /usr/lib64/pgsql/postgresql-9.4/bin/ -B /usr/bin -d
/db/pgsql/data.old -D /db/pgsql/data
Have no idea as I am confused as to your layout and what you have done, so:
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).
1) Did you run the Fedora postgresql-setup upgrade command at any time?
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*

the probable cause of the failure.

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.
UPDATE:
with the idea to start my database with postgres 9.4 then dump the
databse. I run:
$ /usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl -D /db/pgsql/data-9.4 start
but it returns this error:
FATAL: 58P01: could not access file "pg_stat_statements": No such
file or directory
$ ls -al data-9.4/pg_stat
.......
-rw------- 1 postgres postgres 905 Jul 9 15:36 pg_stat_statements.stat
Why do I have this error then ?
Please let's not introduce new errors until we figure out the existing
errors and setup.
