# @summary Manages initdb feature for a postgresql::server instance
#
# @param auth_host auth method used by default for host authorization
# @param auth_local auth method used by default for local authorization
# @param data_checksums Boolean. Use checksums on data pages to help detect corruption by the I/O system that would otherwise be silent.
# @param datadir PostgreSQL data directory
# @param encoding
# Sets the default encoding for all databases created with this module.
# On certain operating systems this is also used during the template1 initialization,
# so it becomes a default outside of the module as well.
# @param group Overrides the default postgres user group to be used for related files in the file system.
# @param initdb_path Specifies the path to the initdb command.
# @param lc_messages locale used for logging and system messages
# @param locale Sets the default database locale for all databases created with this module.
# On certain operating systems this is used during the template1 initialization as well, so it becomes a default outside of the module.
# Warning: This option is used during initialization by initdb, and cannot be changed later.
# If set, checksums are calculated for all objects, in all databases.
# @param logdir PostgreSQL log directory
# @param manage_datadir Set to false if you have file{ $datadir: } already defined
# @param manage_logdir Set to false if you have file{ $logdir: } already defined
# @param manage_xlogdir Set to false if you have file{ $xlogdir: } already defined
# @param module_workdir Working directory for the PostgreSQL module
# @param needs_initdb Explicitly calls the initdb operation after server package is installed
# and before the PostgreSQL service is started.
# @param user Overrides the default PostgreSQL super user and owner of PostgreSQL related files in the file system.
# @param username username of user running the postgres instance
# @param xlogdir PostgreSQL xlog/WAL directory
# @param port
# Specifies the port for the PostgreSQL server to listen on.
# Note: The same port number is used for all IP addresses the server listens on. Also, for Red Hat systems and early Debian systems,
# changing the port causes the server to come to a full stop before being able to make the change.
# @param psql_path Specifies the path to the psql command.
