We would like to draw your attention to this in-depth article, written on the basis of real-world experience, and devoted to a rarely discussed topic: migration from Firebird to PostgreSQL.
The article breaks down 23 real-world problems that catch teams off guard - like how PostgreSQL can make simple updates run 17 times slower than Firebird, or why your backup strategy will need a complete overhaul, and why you will need to rewrite all your triggers. It's not about bashing PostgreSQL (which is an excellent database), but rather giving DBAs, CTOs, and developers a clear picture of what they're signing up for.
The article is available in English, German, and Portuguese:
