Remove gratuitous references to postmaster program

2023-01-26T09:48:32+00:00

"postgres" has long been officially preferred over "postmaster" as the
name of the program to invoke to run the server.  Some example scripts
and code comments still used the latter.  Change those.

start-scripts: switch to $PGUSER before opening $PGLOG.

2017-11-06T15:11:10+00:00

By default, $PGUSER has permission to unlink $PGLOG.  If $PGUSER
replaces $PGLOG with a symbolic link, the server will corrupt the
link-targeted file by appending log messages.  Since these scripts open
$PGLOG as root, the attack works regardless of target file ownership.

"make install" does not install these scripts anywhere.  Users having
manually installed them in the past should repeat that process to
acquire this fix.  Most script users have $PGLOG writable to root only,
located in $PGDATA.  Just before updating one of these scripts, such
users should rename $PGLOG to $PGLOG.old.  The script will then recreate
$PGLOG with proper ownership.

pg_ctl: Change default to wait for all actions

2017-01-14T14:15:08+00:00

The different actions in pg_ctl had different defaults for -w and -W,
mostly for historical reasons.  Most users will want the -w behavior, so
make that the default.

Remove the -w option in most example and test code, so avoid confusion
and reduce verbosity.  pg_upgrade is not touched, so it can continue to
work with older installations.

Updates to reflect that pg_ctl stop -m fast is the default

2017-01-14T02:25:36+00:00

Various example and test code used -m fast explicitly, but since it's
the default, this can be omitted now or should be replaced by a better
example.

pg_upgrade is not touched, so it can continue to operate with older
installations.

Make whitespace consistent inside some script files

2017-01-12T15:17:37+00:00

I don't know what the global standard might be, but at least adjacent
code should use the same whitespace.

Fix typo in linux startup script.

Missed a "$" in what was meant to be a variable substitution.  Careless
mistake in commit f23425fa950fec3aff458de117037c9caadbc35c.

Improve handling of OOM score adjustment in sample Linux start script.

Per a suggestion from Christoph Berg.

Improve our mechanism for controlling the Linux out-of-memory killer.

2014-06-19T00:12:51+00:00

Arrange for postmaster child processes to respond to two environment
variables, PG_OOM_ADJUST_FILE and PG_OOM_ADJUST_VALUE, to determine whether
they reset their OOM score adjustments and if so to what.  This is superior
to the previous design involving #ifdef's in several ways.  The behavior is
now available in a default build, and both ends of the adjustment --- the
original adjustment of the postmaster's level and the subsequent
readjustment by child processes --- can now be controlled in one place,
namely the postmaster launch script.  So it's no longer necessary for the
launch script to act on faith that the server was compiled with the
appropriate options.  In addition, if someone wants to use an OOM score
other than zero for the child processes, that doesn't take a recompile
anymore; and we no longer have to cater separately to the two different
historical kernel APIs for this adjustment.

Revert "pg_ctl: Add idempotent option"

2013-04-30T01:55:12+00:00

This reverts commit 87306184580c9c49717b00d48a2f9e717f21e0a8.  The
behavior in certain cases is still being debated, and it's too late to
solve this before beta.

Don't try to pass -I switch to postmaster in contrib/start-scripts/linux.
