Ok, thank you very much about your help rjlee
But I fixed the problem that took me 1 week solved, I will post here to help persons like me that are not still guru in this area
so, it will help anyway
My server were working good, I could access, creater, modify and delete tables, db's and more, actually I had 4 db's that I was working
Some day I dicide to install the free forum downloaded from internet (
http://www.funkboard.co.uk) and suddenly I could access to my db's and I start postting help in any forum that I found aboud this
so the simple solution about this were that the owner of all directories and files were change and the group it keep the same(postgres)
I got:
drwx------ 9 78 postgres 4096 Apr 4 22:14 base/
drwx------ 2 78 postgres 4096 Apr 12 16:36 global/
drwx------ 2 78 postgres 4096 Oct 20 12:48 pg_clog/
-rw------- 1 78 postgres 3533 Apr 5 22:11 pg_hba.conf
-rw------- 1 78 postgres 1441 Oct 20 12:47 pg_ident.conf
-rw------- 1 78 postgres 4 Oct 20 12:47 PG_VERSION
drwx------ 2 78 postgres 4096 Mar 21 21:35 pg_xlog/
-rw------- 1 78 postgres 7815 Apr 6 00:30 postgresql.conf
-rw------- 1 78 postgres 47 Apr 12 16:34 postmaster.opts
-rw------- 1 78 postgre 45 Apr 12 16:34 postmaster.pid
so, instead having owner postgres I was having 78, so I just change with
# chown postgres -R /var/lib/pgsql
and NOW is working, what happy I am now
thanks you all and the forum by having this cool tool
