services.postgresql.ensureUsers.*.ensureClauses.login

Grants the user, created by the ensureUser attr, login permissions. From the postgres docs:

Only roles that have the LOGIN attribute can be used as the initial role name for a database connection. A role with the LOGIN attribute can be considered the same as a “database user”. To create a role with login privilege, use either:

CREATE ROLE name LOGIN; CREATE USER name;

(CREATE USER is equivalent to CREATE ROLE except that CREATE USER includes LOGIN by default, while CREATE ROLE does not.)

Type

null or boolean

Default
