classKeywordTable

final class KeywordTable

Restricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.

The words PostgreSQL's scanner turns into keyword tokens.

Every keyword is its own terminal in gram.y; whether it may also serve as an identifier is the grammar's business, not the scanner's.
