Usage
This page describes how to use the features of the Postgres crate. Not all features are currently covered
The postgres crate stores configuration in a settings map, that looks like
(postgres/settings (postgres/settings-map {:version "8.4"
:permissions [{:connection-type "local" :database "all" :user "all" :auth-method "trust"}]}))The settings perform no actions, they only provide data for other functions in the crate to consume. Settings may contain the keys :version, :permissions, :options, :recovery.
Permissions specify the contents of the pg_hba file. Familiarity with the pg_hba.conf file format is assumed here. For more information, see http://www.postgresql.org/docs/9.0/interactive/auth-pg-hba-conf.html
Permissions is a seq of records, each record is a map, that looks like
{:connection-type "local" :database "all" :user "all" :auth-method "trust"}The required keys are :connection-type, :database, :user, :auth-method. The optional keys are :ip-mask and :auth-options.
A record can also be a vector
["local" "all "all" "trust"]The arguments must be in the same order as in a traditional pg_hba.conf
A non-comprehensive list of functions that are useful. In all cases, the doc strings are helpful.
-
(postgres)Installs postgres -
(hba-conf)writes the pg_hba.conf file, based on the contents of :permissions in settings. -
(postgresql-conf)writes the postgresql.conf file, based on the contents of :options (init-db)(create-database)(create-role)-
(service)Start, stop, restart the postgres service. Note that order is important here, so it may be useful to restart postgres after e.g. writing pg_hba.conf
