Boolean parity is driving real migration chatter in the database world. Oracle added the native BOOLEAN data type in 23ai, while PostgreSQL had BOOLEAN from inception [1].
Boolean parity in practice: Oracle vs PostgreSQL — The Oracle move marks a milestone in cross-database parity, but PostgreSQL's longstanding support shows timelines can diverge [1]. That gap nudges teams to plan migrations with cross-database compatibility in mind, especially for apps that switch between engines. For teams running polyglot stacks, the mismatch becomes a practical hurdle when writing portable SQL [1].
UUIDv7 and the database-use debate — A post titled Fixing UUIDv7 (for database use-cases) adds to the debate about using UUIDv7 in databases [2]. The discussion invites engineers to weigh identity schemes against real workloads [2].
Migration decisions hinge on feature timelines — Together, these threads show that feature timelines shape migration decisions and vendor strategies [1][2]. The parity question isn't just about what's supported; it's about when and how teams move workloads to new tech stacks. Vendors respond with roadmap ideas and compatibility plans to reassure customers facing cross-database migrations.
Parity work will continue as vendors ship more native data types and identity schemes. Keep an eye on how Oracle and PostgreSQL navigate the next wave of feature parity.
