Hello PostgreSQL hackers,
I'm forwarding an extract of a message from the cygwin mailing list.
The thread which started the message was:
http://www.cygwin.com/ml/cygwin/2004-07/msg00712.html
The problem is illustrated below:
(If it's of any use, Cygserver has been run successfully and CYGWIN=server was set.)
-------FORWARDED MESSAGE ------------
$ initdb -D /usr/share/postgresql/data
The files belonging to this database system will be
owned by user "admin".
This user must also own the server process.

What does the line
"FATAL: shmat(id=1179648) failed: Invalid argument".
mean?
Thanks!

Thanks Carlo Florendo y Flora and Igor Pechtchanski
for your very illustrative comments. Based on that I
follow the procedure again for install PostgreSQL in
my Window ME. Now I can run Cygserver but The
initialization of PostgreSQL failled. See the output I
got:
--------------------------------
admin@alejo ~
$ CYGWIN=server
admin@alejo ~
$ export CYGWIN
admin@alejo ~
$ /usr/sbin/cygserver &
[1] 901443
admin@alejo ~
$ cygserver: Initialization complete. Waiting for
requests.
// I had to press ENTER because the System really was
wainting for something
admin@alejo ~
$ initdb -D /usr/share/postgresql/data
The files belonging to this database system will be
owned by user "admin".
This user must also own the server process.
The database cluster will be initialized with locale
C.

---------------------------------------
Really I don't know what does meant the line "FATAL:
shmat(id=1179648) failed: Invalid argument".
What difficult is becoming the installation of the
PostgreSQL'new versions on Cygwin (runing on Windows
ME) since the use of Cygserver instaed of ipc-daemon2.
Maybe I am doing something wrong but I don't know what
it is.
I am not an expert just a user.
Somebody have any clue?
