Compatibility
- The draft SQL:2008 standard includes a TRUNCATE command,
- but at this writing it is uncertain whether that will reach standardization
- or be fully compatible with PostgreSQL's
- implementation.
+ The SQL:2008 standard includes a TRUNCATE command with the syntax
+ TRUNCATE TABLE tablename.
+ The clauses CONTINUE IDENTITY/RESTART IDENTITY
+ also appear in that standard but have slightly different but related meanings.
+ Some of the concurrency behavior of this command is left implementation-defined
+ by the standard, so the above notes should be considered and compared with
+ other implementations if necessary.
