Functionality-wise, this candidate solution is most limited compared to others. But it is part of the standard (ISO/IEC TR 19075-6:2017) and PostgreSQL is also working on its support. It was implemented and reverted due to regression in PostgreSQL 15, and added back in PostgreSQL 16 (not released yet, so another revert is possible).
Similar to PostgreSQL, we do not support parsing
JSON input clause
(FORMAT JSON [ ENCODING { UTF8 | UTF16 | UTF32 } ]
) beforeIS
. The constraintWITH UNIQUE KEYS
can be parsed but not supported for evaluation.Checklist
