The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/12/mvcc-intro.html Description:
The documentation page: __https://www.postgresql.org/docs/12/mvcc-intro.html makes a reference to the term "innovative Serializable Snapshot Isolation (SSI) level" I can't find that anywhere in the documentation. I am expecting to find it here: __https://www.postgresql.org/docs/12/transaction-iso.html or here: __https://www.postgresql.org/docs/current/sql-set-transaction.html But there is nothing. A search for the term "innovative Serializable Snapshot Isolation (SSI) level": __https://www.postgresql.org/search/?q=Serializable+Snapshot+Isolation+ produces a lengthy listing, demonstrating that the term is used throughout the documentation. But there is no entry in the documentation that defines the term, or that defines the commands required to use it. It is important to know: a. if this is an ANSI/ISO/SQL Transaction Isolation Level b. or if it is an extension c. or if it is neither d. how to use it
