PostgreSQL
In PostgreSQL storage backend, Vault data will be stored in PostgreSQL. Vault documentation for PostgreSQL storage can be found in here.

namespace: demo

spec.backend.postgresql
To use PostgreSQL as backend storage in Vault specify spec.backend.postgresql in VaultServer CRD.
spec:

postgresql:
connectionURLSecret: <secret_name>

Here, we are going to describe the various attributes of the spec.backend.postgresql field.
postgresql.connectionURLSecret
postgresql.connectionURLSecret is a required field that specifies the name of the secret containing the connection string to use to authenticate and connect to PostgreSQL. The secret contains the following key:
connection_url
spec:
backend:
postgresql:
connectionURLSecret: "my-postgres-conn"
postgresql.table
postgresql.table is an optional field that specifies the name of the table in which to write Vault data. If it is not specified, then Vault will set the value vault_kv_store. Vault will not create the table, so this table must exist in the database.
spec:
backend:
postgresql:
table: "vault_data"
postgresql.maxParallel
maxParallel is an optional field that specifies the maximum number of parallel operations to take place. This field accepts integer value. If this field is not specified, then Vault will set value to 128.
spec:
backend:
postgresql:
maxParallel: 124
