Module shared 

Helpers shared by all AST → IR builders.

• Schema-qualified name resolution (with -- @pgevolve schema= defaulting).
• Type-name stringification (so crate::ir::column_type::ColumnType::parse_from_pg_type_string can decide the canonical form).
• Default-expression classification (literal vs. nextval vs. arbitrary expr).

Functions

build_default_expr

Convert a column-default expression node into a DefaultExpr.

ident

Build an unquoted Identifier, wrapping crate::ir::IrError into a source-located ParseError::Ir.

qname_from_string_list

Resolve a repeated Node type-name list (as produced by CreateEnumStmt, CreateDomainStmt, CompositeTypeStmt, etc.) into a QualifiedName.

render_type_name_to_string

Render a pg_query::TypeName into a string ColumnType::parse_from_pg_type_string can consume.

resolve_qname

Resolve a RangeVar into a QualifiedName, filling in default_schema when the source did not qualify the object.

type_name_to_column_type

Convert a TypeName into a ColumnType, propagating parser errors.
