postmaster does not know where to find the database system data.
You must specify the directory that contains the database system
either by specifying the -D invocation option or by setting the
PGDATA environment variable.

[nicola@localhost root]$

Prova così:

/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l /tmp/pgsql.log start
