Problem Description:
Custom RDS ParameterGroups can prevent doing in-place upgrades of PGSQL RDS DBs. Appears upgrades work when using default ParameterGroups (at least when executed outside the CFn context). Need to add a toggle for flipping back and forth between custom and generic when doing stack-updates
Expected Behavior:
Upgrading from 9.x to 10.x succeeds even if custom ParameterGroups are attached.
Actual Behavior:
Upgrading from 9.x to 10.x may fail if custom ParameterGroups are attached.
Fix recommendation:
Add a toggle to RDS template to flip between custom and default ParameterGroup for use during CFn-managed DB version upgrades.
