A PostgreSQL alternative should be evaluated against the application's actual contract. SQL support alone does not guarantee equivalent transactions or extensions.

Trial

Import representative schema and data, including constraints, indexes, and timezones.
Run critical queries at realistic concurrent read/write load.
Test multi-statement transactions, isolation, uniqueness, and failure rollback.
Check extensions, JSON behavior, full-text search, migrations, and driver compatibility.
Rehearse backup, point-in-time recovery, replication failure, and export back to PostgreSQL.

Document each semantic mismatch. A faster single query is not a fair trade if writes or recovery no longer meet the application's requirements.
