While defining parameter group for an RDS cluster in CloudFormation like this:
"TestDBParameterGroup": {
"Type": "AWS::RDS::DBParameterGroup",
"Properties": {
"Description": "my parameter group with logical replication on",
"Family": "aurora-postgresql11",
"Parameters": {
"rds.logical_replication": true
},
"Tags": [
{
"Key": "hiya:billto:costcenter",
"Value": "my-costcenter"
},
{
"Key": "hiya:billto:product",
"Value": "my-product"
},
{
"Key": "hiya:billto:owner",
"Value": "my-team"
},
{
"Key": "hiya:operations:contact",
"Value": "my-team"
}
]
}
},
...
I get this error: Invalid / Unsupported DB Parameter: rds.logical_replication
When I list parameter groups on the console, this parameter exists. I have used it manually with RDS instances created by hand. I don't know why won't it recognize in CF. I've tried with both values true and 1.
Anyone knows if there's a problem with underscores or dots?
