The postgres_data_dir variable seems not used when initialising the database

[smaiyaki]

I have installed postgres 9.6 on ubuntu 16 with the aid of your ansible role which is great. One thing I have noticed however is that the database is initialised using the data path /var/lib/postgresql/9.6/main regardless of what was set in the variable postgresql_data_dir .

So it seems the database has been silently initialized with the default postgres data path and before the database directory is then set as I can see in the logs

The workaround am using at the moment is to run an rsyn command to copy the data directory using this command below. which introduces some inconsistencies sometimes

service postgresql stop rsync -av /var/lib/postgresql /custom_path/database/data mv /var/lib/postgresql /var/lib/postgresql.bak service postgresql start

Indeed, it is stale, but the issue still exists :-)

That's peculiar, I just installed from official CentOS repo's using this role and overwrote a number of variables, including:

postgresql_data_dir: "/var/lib/pgsql/{{ postgresql_version }}/data"

which correctly initialized the database in /var/lib/pgsql/11/data.

[flo-rian]

I've used the version 13 packages from https://www.postgresql.org/download/linux/redhat/ I used postgresql_config_path: /var/lib/pgsql/13 for config and postgresql_data_dir: /data/postgresql for data but the role fails with

TASK [geerlingguy.postgresql : Configure global settings.] ****************************************************************************
failed: [pn] (item={'option': 'unix_socket_directories', 'value': '/var/run/postgresql'}) => {"ansible_loop_var": "item", "changed": false, "item": {"option": "unix_socket_directories", "value": "/var/run/postgresql"}, "msg": "Destination /var/lib/pgsql/13/postgresql.conf does not exist !", "rc": 257}

It turns out the config dir only contains an empty backup and data directory and all the config ends up in the data directory.

Running the "{{ postgresql_bin_path }}/initdb -D {{ postgresql_data_dir }}" command creates all config file inside the data directory. This seems a bit odd to me. I know it is not the distribution install but the official packages from postgresql. So I assume the role should work with that. Is it a bug of the postgresql packages? Anyone got experience with other versions of postgresqlpackages?

I can confirm that this is an issue with Postgresql 13. I tried it with 12 and the custom postgres_data_dir works fine.

[syswipe]

I defined postgresql_data_dir and it doesn't work. custom data dir was successfully initialized, but PostgreSQL still starts with the default one

[christopheg]

This worked for me:

postgresql_global_config_options:
  - option: data_directory
    value: "/custom/data/dir"

postgresql_data_dir: /custom/data/dir		

The postgresql_data_dir variable only initializes a database in the given directory.

[captain-proton]

@christopheg solution worked for me (Ubuntu 20). The database gets initialized in the directory set through postgresql_data_dir, but is not used in the postgresql.conf. The variable should be handled in the task Configure global settings or afterwards.

[MichaelDBA]

Is this still an issue for using a custom data directory?

I can't install postgresql-14 because in some places role uses correct version of pg (14) but sometimes uses version 13.
