# Start PostgreSQL
|
|
# ==================================================================
|
|
# Setting all necessary configuration options via `pg_ctl` (which
|
|
# is basically a wrapper around `postgres`) instead of editing
|
|
# `postgresql.conf` directly with `sed`. See docs:
|
|
#
|
|
# + https://www.postgresql.org/docs/current/app-pg-ctl.html
|
|
# + https://www.postgresql.org/docs/current/app-postgres.html
|
|
#
|
|
# See more on the caveats at
|
|
# https://discourse.nixos.org/t/how-to-configure-postgresql-declaratively-nixos-and-non-nixos/4063/1
|
|
# but recapping out of paranoia:
|
|
#
|
|
# > use `SHOW` commands to check the options because `postgres -C`
|
|
# > "_returns values from postgresql.conf_" (which is not changed by
|
|
# > supplying the configuration options on the command line) and
|
|
# > "_it does not reflect parameters supplied when the cluster was
|
|
# > started._"
|
|
#
|
|
# OPTION SUMMARY
|
|
# --------------------------------------------------------------------
|
|
#
|
|
# + `unix_socket_directories`
|
|
#
|
|
# > PostgreSQL will attempt to create a pidfile in
|
|
# > `/run/postgresql` by default, but it will fail as it
|
|
# > doesn't exist. By changing the configuration option
|
|
# > below, it will get created in $PGDATA.
|
|
#
|
|
# + `listen_addresses`
|
|
#
|
|
# > In tandem with edits in `pg_hba.conf` (see
|
|
# > `HOST_COMMON` below), it configures PostgreSQL to
|
|
# > allow remote connections (otherwise only `localhost`
|
|
# > will get authenticated and the rest of the traffic
|
|
# > discarded).
|
|
# >
|
|
# > NOTE: the edit to `pga_hba.conf` needs to come
|
|
# > **before** `pg_ctl start` (or the service
|
|
# > needs to be restarted otherwise), because then
|
|
# > the changes are not being reloaded.
|
|
# >
|
|
# > More info on setting up and troubleshooting remote
|
|
# > PosgreSQL connections (these are all mirrors of the
|
|
# > same text; again, paranoia):
