References

The set of SQL keywords is stored in the character vector .SQL92Keywords and reflects the SQL ANSI/ISO standard as documented in "X/Open SQL and RDA", 1994, ISBN 1-872630-68-8. Users can easily override or update this vector.

PostgreSQL does add some keywords to the SQL 92 standard, they are listed in the .PostgreSQLKeywords object.
