Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Teams

  • Resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives
  • Limited channel structure; maximum of 200 public and 30 private channels per team
  • Cannot invite guest users to specific channels; guest access grants full team visibility
  • Unable to chat during screen sharing; limits real-time collaborative communication
  • Limited customization options for branding and interface; cluttered UX compared to Slack
  • Channels cannot be moved between teams; requires manual replication for reorganization

Postgres

  • Each major version is supported for only 5 years after its initial release, after which it is end-of-life
  • Major version upgrades break on-disk compatibility and require a full dump and reload or the pg_upgrade tool
  • New major versions ship about once a year, so staying supported means a disruptive upgrade cycle
  • Minor releases contain only frequently-encountered bug fixes, low-risk fixes, security issues and data corruption fixes, so feature gaps are not addressed within a major version
  • There is no vendor SLA; commercial support must be bought separately from third party professional services listed by the project
