The original title is "Building a Production Grade AWS Infrastructure Project (Part 5): RDS"

Short summary

Part 5 of a production AWS infrastructure series covers setting up RDS with Terraform, including module design, PostgreSQL parameter group configuration, and lessons learned from MySQL-centric community module defaults. Key takeaways include pinning minor engine versions, using engine-specific parameter groups, and avoiding string-vs-integer type mismatches in Terraform provider arguments.

• •RDS module requires only security group and subnet IDs as inputs for minimal interface
• •Pin PostgreSQL minor versions and use engine-specific parameter groups, not MySQL defaults
• •Removed MariaDB audit plugin defaults; connection logging via parameter group is sufficient for this project
