Thread: Doc updates
OK, can someone confirm which items still need to be done to update the
documentation?
I can't imagine they are all done, and I don't think we can release 7.0
without them all being done.

I have written a man page for pg_ctl (see below). However, it's still
in a plain text, not marked up yet. I'm very busy right now, and
probably could start to make it into a SGML after 4/12. Is it too late
for the release schedule of 7.0?

NAME
pg_ctl - starts/stops/restarts postmaster
SYNOPSIS
pg_ctl [-w][-D database_dir][-p path_to_postmaster][-o "postmaster_opts"] start
pg_ctl [-w][-D database_dir][-m [s[mart]|f[ast]|i[mmediate]]] stop
pg_ctl [-w][-D database_dir][-m [s[mart]|f[ast]|i[mmediate]][-o "postmaster_opts"] restart
pg_ctl [-D database_dir] status
DESCRIPTION
pg_ctl is a utility for starting, stopping or restarting postmaster.
Starting postmaster
To start postmaster:
pg_ctl start
If -w is supplied, pg_ctl waits for the database server comes up, by
watching for creation of the pid file (PGDATA/postmaster.pid), for up
to 60 seconds.
Parameters to invoke postmaster are taken from following sources:
Path to postmaster: found in the command search path
Database directory: PGDATA environment variable
Other parameters: PGDATA/postmaster.opts.default
postmaster.opts.default contains parameters for postmaster. With a
default installation, the "-S" option is enabled. So "pg_ctl start"
implies:
postmaster -S
Note that postmaster.opts.default is installed by initdb from
lib/postmaster.opts.default.sample under the PostgreSQL installation
directory (lib/postmaster.opts.default.sample is copied from
src/bin/pg_ctl/postmaster.opts.default.sample while installing
PostgreSQL).
To override default parameters you can use -D, -p and -o options.
-D database_dir
specifies the database directory
-p path_to_postmaster
specifies the path to postmaster
-o "postmaster_opts"
specifies any parameters for postmaster
Examples:
# blocks until postmaster comes up
pg_ctl -w start
# specifies postmaster path
pg_ctl -p /usr/local/pgsq/bin/postmaster start
# uses port 5433 and disables fsync
pg_ctl -o "-o -F -p 5433" start
Stopping postmaster
pg_ctl stop
stops postmaster.
There are several options for the stopping mode.
-w
waits for postmaster to shut down
-m [s[mart]|f[ast]|i[mmediate]]
specifies the shutdown mode. smart mode waits for all
the clients to logout. This is the default.
fast mode sends SIGTERM to the backends, that means
active transactions get rolled back. immediate mode sends SIGUSR1
to the backends and lets them abort. In this case, database recovery
will be neccessary on the next startup.
Restarting postmaster
This is almost equivalent to stopping postmaster then starting it
again except that the parameters for postmaster used before stopping
it would be used too. This is done by saving them in
PGDATA/postmaster.opts file. -w, -D, -m, -fast, -immediate and -o
can also be used in the restarting mode and they have same meanings as
described above.
Examples:
# restarts postmaster in the simplest form
pg_ctl restart
# restarts postmaster, waiting for it to shut down and to come up
pg_ctl -w restart
# uses port 5433 and disables fsync next time
pg_ctl -o "-o -F -p 5433" restart
Getting status from postmaster
To get status information from postmaster:
pg_ctl status
Following is sample outputs from pg_ctl.
pg_ctl: postmaster is running (pid: 13718)
options are:
/usr/local/src/pgsql/current/bin/postmaster
-p 5433
-D /usr/local/src/pgsql/current/data
-B 64
-b /usr/local/src/pgsql/current/bin/postgres
-N 32
-o '-F'

I'll be happy to mark up what is available. Can I use what you
included in the email? If so, I'll go ahead and put it in...
