32-35: Document and alphabetize new module input.
Themax_database_connectionsinput was added to thedatabasemodule, but it isn’t mentioned in our docs/README. Please:
- Update your Terraform documentation to include this variable.
- (Optional) Reorder module inputs alphabetically for readability.

32-39: Dynamic block fordatabase_flagsis correctly scoped.
The conditional addition of themax_connectionsflag based onvar.max_database_connectionsis implemented correctly inside thesettingsblock. This ensures the flag is only set when provided.

🛠️ Refactor suggestion
Consider using a numeric type or adding validation for max_database_connections.
Right now this variable is a string with an empty default. Since it ultimately represents a numeric value for the max_connections flag, we should:
- Change the type to
numberwith a default ofnulland update the dynamic block to check for!= null. - Or add a
validationblock to enforce a digits-only string (e.g.^[0-9]+$).
This ensures users can’t pass invalid inputs and improves type safety.
variable "max_database_connections" {
description = "The maximum number of connections to the database"
- type = string
- default = ""
+ type = number
+ default = null
+ validation {
+ condition = var.max_database_connections == null || var.max_database_connections >= 0
+ error_message = "max_database_connections must be a non-negative number or null"
+ }

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion
Align module variable type with root or add validation.
Just like in the root, the database module’s max_database_connections should either:
- Be converted to a
numberwithdefault = nulland validation, or - Retain
stringtype but include avalidationclause to enforce numeric content.
Consistency prevents runtime errors when passing values across modules.
variable "max_database_connections" {
description = "The maximum number of connections to the database"
- type = string
- default = ""
+ type = number
+ default = null
+ validation {
+ condition = var.max_database_connections == null || var.max_database_connections >= 0
+ error_message = "max_database_connections must be a non-negative number or null"
+ }
