The following table lists all of the [compound PL/pgSQL executable statements](../../../../../syntax_resources/grammar_diagrams/#plpgsql-compound-stmt).
- The _Statement Name_ column links to the page where the semantics are described.
- The _Syntax rule name_ column links to the definition on the omnibus [Grammar Diagrams](../../../../../syntax_resources/grammar_diagrams/) reference page.
