mcstans installed and started, this solved many problems.
Actually i'm running SE-PostgreSQL on my server host with phpPgAdmin
on the same host but browsed from my workstation.
Now i can enter the parameters from the database and setup my blog engine, thx.
It remains some Selinux denials with sendmail (dotclear want to send a
mail to the admin of the blog engine and with phpPgAdmin
Selinux denials with sendmail:

This error also appears all the time with phpPgAdmin but with a
different name={dotclear,template1} . The second one appears when I
want to delete a unused database:
-------------------------
Erreur SQL :
ERROR: SELinux: denied { set_param }
scontext=system_u:system_r:httpd_t
