Enum RelationInheritance 

pub enum RelationInheritance {
    Plain,
    Descendants,
    Only(OnlySyntax),
}

PostgreSQL relation_expr inheritance marker on a table reference: whether a query reaches the relation’s descendant (inheritance-child) tables, plus the source spelling that asked for it.

One canonical shape for the four legal relation_expr spellings, chosen so the impossible ONLY name * combination is structurally unrepresentable: the * and ONLY markers are sibling variants that can never co-occur. Plain and Descendants are semantically identical in PostgreSQL (both leave inh = true, so a bare t and an explicit t * select the same rows); the distinct variant exists only to round-trip the source * exactly.

Variants

Plain

Bare name: descendant tables included implicitly.

Descendants

name *: descendant tables included via the explicit legacy star marker.

Only(OnlySyntax)

ONLY name / ONLY (name): descendant tables suppressed.
