Nothing can happen to a database unless the
postmaster
process is running. As the site administrator, there
are a number of things you should remember before
starting the postmaster.
These are discussed in the installation and configuration sections
of this manual.
However, if Postgres has been installed by following
the installation instructions exactly as written, the
following simple command is all you should
need to start the postmaster:
% postmaster
The postmaster occasionally prints out
messages which
are often helpful during troubleshooting. If you wish
to view debugging messages from the postmaster,
you can
start it with the -d option and redirect the output to
the log file:
% postmaster -d > pm.log 2>&1 &
If you do not wish to see these messages, you can type
% postmaster -S
and the postmaster will be "S"ilent.
No ampersand ("&") is required in this case, since the postmaster
automatically detaches from the terminal when -S is specified.
