I installed Red Hat 5.2 EL. During the install I select postgresql and this versoin was installed: postgresql-8.1.11-1.el5_1.1. 1. I started postgresql as follows: initdb -D /var/lib/pgsql/data 2. I started the database server as follows: /usr/bin/pg_ctl -D /var/lib/pgsql/data -l logfile start 3. I started the postmaster as follows: service postgresql start When I check that it is all running with ps command I get: 324 pts/1 S 0:00 /usr/bin/postmaster -D /var/lib/pgsql/data When I did the same setps in fedora 8 the postmaster was started on a port 1703 ? S 0:01 /usr/bin/postmaster -p 5432 -D /var/lib/pgsql/data Why is there no -p 5432 on the red hat box? I assume the port is needed. What do I need to do to have the postmaster running on port 5432 like on the fedora box? Thanks Marc
