core: Add compatibility with PG 12 major version
This PR adds compatibility for postgresql 12 major version. The PG12 configuration is as close as the PG11 one. All defaults have been kept back to avoid breaking backward compatibility within this ansible role. Here is a complete side-by-side diff between the current PG11 conf and the new PG12 conf: ```diff # 0 selects the syste # 0 selects the syste > #tcp_user_timeout = 0 # TCP_USER_TIMEOUT, i > # 0 selects the syste > #ssl_min_protocol_version = 'TLSv1' > #ssl_max_protocol_version = '' > #shared_memory_type = mmap # the default is the > # supported by the op > # mmap > # sysv > # windows > # (change requires re dynamic_shared_memory_type = posix # the default is the dynamic_shared_memory_type = posix # the default is the # supported by the op # supported by the op # posix # posix # sysv # sysv # windows # windows # mmap # mmap # use none to disable < # (change requires re # (change requires re wal_level = logical # minimal, replica, o | wal_level = {{ postgres_wal_level }} # min # (change requires re # (change requires re wal_log_hints = on # also do full page w wal_log_hints = on # also do full page w # (change requires re # (change requires re > #wal_init_zero = on # zero-fill new WAL f > #wal_recycle = on # recycle WAL files # (change requires re # (change requires re > # - Archive Recovery - > > # These are only used in recovery mode. > > {% if postgres_primary %} > {# In PG < 12 versions all the recovery settings were in a se > restore_command = '/usr/bin/barman-wal-restore --user barman > # placeholders: %p = path of > # %f = file nam > # e.g. 'cp /mnt/server/archiv > # (change requires restart) > {% else %} > #restore_command = '' # command to use to restore a > # placeholders: %p = path of > # %f = file nam > # e.g. 'cp /mnt/server/archiv > # (change requires restart) > {% endif %} > #archive_cleanup_command = '' # command to execute at every > #recovery_end_command = '' # command to execute at compl > > # - Recovery Target - > > # Set these only when performing a targeted recovery. > > #recovery_target = '' # 'immediate' to end recovery > # consistent state is reached > # (change requires restart) > #recovery_target_name = '' # the named restore point to > # (change requires restart) > #recovery_target_time = '' # the time stamp up to which > # (change requires restart) > #recovery_target_xid = '' # the transaction ID up to wh > # (change requires restart) > #recovery_target_lsn = '' # the WAL LSN up to which rec > # (change requires restart) > #recovery_target_inclusive = on # Specifies whether to stop: > # just after the specified re > # just before the recovery ta > # (change requires restart) > {% if postgres_primary %} > {# In PG < 12 versions all the recovery settings were in a se > recovery_target_timeline='latest' # 'current', 'latest' > # (change requires restart) > {% else %} > #recovery_target_timeline = 'latest' # 'current', 'latest' > # (change requires restart) > {% endif %} > #recovery_target_action = 'pause' # 'pause', 'promote', > # (change requires restart) max_wal_senders = 10 # max number of walsender pro | #max_wal_senders = 10 # max number of walsender pro # (change requires restart) # (change requires restart) > {% if postgres_primary %} > {# In PG < 12 versions this setting was defined in separate r > primary_conninfo = 'host={{ postgres_primary.host }} port={{ > # (change requires re > {% else %} > #primary_conninfo = '' # connection string t > # (change requires re > {% endif %} > #primary_slot_name = '' # replication slot on > # (change requires re > {% if postgres_primary %} > {# In PG < 12 versions this setting was defined in separate r > promote_trigger_file = '/var/lib/postgresql/{{ postgres_versi > {% else %} > #promote_trigger_file = '' # file name whose pre > {% endif %} # retrieve WAL after # retrieve WAL after > #recovery_min_apply_delay = 0 # minimum delay for a > #plan_cache_mode = auto # auto, force_generic > # force_custom_plan > # debug5 < # debug4 < # debug3 < # debug2 < # debug1 < # log < # notice < # warning < # error < < log_min_duration_statement = 10000 # -1 is disabled, 0 l log_min_duration_statement = 10000 # -1 is disabled, 0 l # and their durations # and their durations # statements running # statements running # of milliseconds # of milliseconds > #log_transaction_sample_rate = 0.0 # Fraction of transac > # are logged regardle > # statements from all > #client_min_messages = notice # values in order of > # debug5 > # debug4 > # debug3 > # debug2 > # debug1 > # log > # notice > # warning > # error # only default tables # only default tables > #default_table_access_method = 'heap' > # selects precise out > #data_sync_retry = off # retry or panic on f > # data? > # (change requires re > # assignments, so they can usefully be given more than once. ```

3# PostgreSQL configuration file
4# -----------------------------
5#
6# This file consists of lines of the form:
7#
8# name = value
9#
10# (The "=" is optional.) Whitespace may be used. Comments are introduced with
11# "#" anywhere on a line. The complete list of parameter names and allowed
12# values can be found in the PostgreSQL documentation.
13#
14# The commented-out settings shown in this file represent the default values.
15# Re-commenting a setting is NOT sufficient to revert it to the default value;
16# you need to reload the server.
17#
18# This file is read on server startup and when the server receives a SIGHUP
19# signal. If you edit the file on a running system, you have to SIGHUP the
20# server for the changes to take effect, run "pg_ctl reload", or execute
21# "SELECT pg_reload_conf()". Some parameters, which are marked below,
22# require a server shutdown and restart to take effect.
23#
24# Any parameter can also be given as a command-line option to the server, e.g.,
25# "postgres -c log_connections=on". Some parameters can be changed at run time
26# with the "SET" SQL command.
27#
28# Memory units: kB = kilobytes Time units: ms = milliseconds
29# MB = megabytes s = seconds
30# GB = gigabytes min = minutes
