OK now I really need help. I tried to install version 9.4.4-2 of
Postgres with
ftp://www.fruitbat.org/pub/cygwin/circa/2015/09/25/151012/index.html,
but now it won't start. I also tried to install 9.4.4-1 but that won't
work either. I also tried to exit all Cygwin processes and run 'dash'
and 'rebaseall', but it didn't help. How do I install an old version of
Postgres 9.4 to upgrade to 9.5?

$ /usr/sbin/postgres --version
postgres (PostgreSQL) 9.4.4

$ /usr/sbin/postgres
FATAL:  could not create shared memory segment: Function not implemented
DETAIL:  Failed system call was shmget(key=5432001, size=40, 03600).

$ /setup-x86 -X -q -P postgresql-9.4.4-1
note: Hand installation over to elevated child process.

$ /usr/sbin/postgres --version
postgres (PostgreSQL) 9.4.4

$ /usr/sbin/postgres
FATAL:  could not create shared memory segment: Function not implemented
DETAIL:  Failed system call was shmget(key=5432001, size=40, 03600).

have you configured cygserver as service and run it ?

The shared memory capability depends on cygserver.

postgresql - How do I upgrade Postgres database in Cygwin? - Server Fault

[-- Attachment #1: Type: text/plain, Size: 597 bytes --]

Can you please change the Postgres packages to use postgres94,
postgres95, postgres96, etc. names? Each version is incompatible with
the previous. This will allow installing Postgres in separate binary
directories to enable upgrades. Alternatively, please increase the
'previous version' history to allow installing old versions. Setup only
has 1 previous version, and if the current version is 9.5.2 and the
previous version is 9.5.1, then there is no way (or very difficult) to
install 9.4!

Hi Chloe,

setup can only manage 1 previous version anyway.

postgres94, postgres95, postgres96 solution will force me to maintain
multiple versions, and I have not the bandwith to manage that.

I uploaded again the 9.4.5 previous version at
   http://matzeri.altervista.org/

You can use that for downgrade your installation.

Marco

PS: I suggest you to subscribe

so that future upgrade won't catch you by surprise anymore.
