I am unable to pass the parameters of parameter group from a variable to module. Is there a specific format that I need to use to pass the "name & value" of db_parameter_group

parameter = ["${var.parameters}"]

@phanindra2407 How are you passing your parameters?

I have a working setup with the following variables passed to the module:

module "db" {
    source = "terraform-aws-modules/rds/aws"
    engine            = "postgres"
    engine_version    = "9.6.3"
    family = "postgres9.6"
    # some stuff removed here for brevity

    parameters = [
        { 
            name = "client_encoding",
            value = "utf8"
        }
    ]
}

@khosrow, Thank you for the response.Below is the way I am trying to code.
module "db" {
source = "terraform-aws-modules/rds/aws"
engine = "postgres"
engine_version = "9.6.3"
family = "postgres9.6"

parameters = ["${var.db_parameters}"]
}

##Passing varibales ##
variable "db_parameters" {
type = "list"
default = [
{
name = "log_connections"
value = 1
},
{
name = "pg.audit"
value = "pg_audit"
}
]
}

I will need to modify these parameters frequently. so cannot hardcode them in the module.

I think the code which @khosrow is writing is correct but the error can be is that you pass incorrect parameters (check AWS RDS documentation for details). This is what I got when I run your code:

* aws_db_parameter_group.this: Error modifying DB Parameter Group: InvalidParameterValue: Could not find parameter with name: pg.audit
	status code: 400, request id: c8a64a1a-aaa6-42a8-99ff-fd04747658ee

If you could update examples/complete/postgres with the failing code which should be actually working then we can have another look. Closing for now.
