Problem installing postgresql in XP with cygwin

Hi,

I'm installinng postgresql in XP with cygwin. I have downloaded the last
version of cygwin today, so the software is up to date.
I have included in the download the packages cygrunsrv and cygipc, in
addition to postgres, of course.

I have created a new user postgres with right to log on as a service.
After I have executed the previous sentence I did in cygwin:

ipc-daemon2 --install-as-service

After that, I have created the directory for the data and make postgres the
owner of it.

and finally I restart the computer and connected with the progress user.

In cygwin again I did the following:

postgres(at)PC_330540 ~
$ initdb -d -D /usr/share/postgresql/data
Running in debug mode.

initdb: internal variables:
PGDATA=/usr/share/postgresql/data
datadir=/usr/share/postgresql
PGPATH=/usr/bin
ENCODING=
ENCODINGID=0
POSTGRES_SUPERUSERNAME=postgres
POSTGRES_BKI=/usr/share/postgresql/postgres.bki
POSTGRES_DESCR=/usr/share/postgresql/postgres.description
POSTGRESQL_CONF_SAMPLE=/usr/share/postgresql/postgresql.conf.sample
PG_HBA_SAMPLE=/usr/share/postgresql/pg_hba.conf.sample
PG_IDENT_SAMPLE=/usr/share/postgresql/pg_ident.conf.sample
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

I have already tested that the Cygwin IPC Daemon 2 is running.

I think that is a problem related with that service but I don't konw where
to continious looking. ¿Any idea?
I don't see any error regarding that service in the XP log.

Thank you and best regards
