postgresql.conf, version 13

PostgreSQLНекоторое время назад подготовил для себя файлик с перечнем всех конфигурационных параметров PostgreSQL — просто скопировал postgresql.conf с тестовой машины.

Потом (для удобства) добавил из этого документа ссылки на документацию каждого параметра — для меня очень удобно переходить по ссылкам из единого документа. Нажал CTRL-F, сразу нашел нужное и перешел на конкретное описание (да, можно в документации искать, но для меня было менее эффективно).

Делал для 12-й версии PostgreSQL, недавно обновил на 13-ю, добавил-удалил лишние-новые параметры. Может кому пригодится.

Эти параметры есть на данной странице (ниже) и в отдельном google-документе, там еще оглавление есть. Если найдете ошибки — пишите в комментах (или в форме обратной связи):

V13 — postgresql.conf (google-docs)

 # -----------------------------

# PostgreSQL configuration file

# -----------------------------

#

# This file consists of lines of the form:

#

#   name = value

#

# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with

# "#" anywhere on a line.  The complete list of parameter names and allowed

# values can be found in the PostgreSQL documentation.

#

# The commented-out settings shown in this file represent the default values.

# Re-commenting a setting is NOT sufficient to revert it to the default value;

# you need to reload the server.

#

# This file is read on server startup and when the server receives a SIGHUP

# signal.  If you edit the file on a running system, you have to SIGHUP the

# server for the changes to take effect, run "pg_ctl reload", or execute

# "SELECT pg_reload_conf()".  Some parameters, which are marked below,

# require a server shutdown and restart to take effect.

#

# Any parameter can also be given as a command-line option to the server, e.g.,

# "postgres -c log_connections=on".  Some parameters can be changed at run time

# with the "SET" SQL command.

#

# Memory units:  kB = kilobytes        Time units:  ms  = milliseconds

#                MB = megabytes                     s   = seconds

#                GB = gigabytes                     min = minutes
