Functions

bind_stored_expression_routines

bind_stored_expression_sites

Apply the sites of a bound copy of expression. Returns whether the syntax changed.

bind_stored_statement_routines

bind_stored_statement_sites

Apply the sites of a bound copy of statement. Returns whether the syntax changed.

copy_stored_source_column_shapes

Apply only planned source aliases and physical columns. The column-dependency binder’s expression normalization is analysis state, not a replacement for the stored query.

fold_assigned_stored_literal

Assignment of a stored unknown literal to target, as coerce_to_target_type converts an untyped constant with the target type’s input function when a default, generation expression or result is analyzed: the literal becomes a constant of the enum or enum-array type, or of that base type of a domain, whose own check applies when the value is assigned. Any other expression is coerced when it is evaluated.

read_unknown_stored_literal

Read an unknown literal with the input function of target, which reports what the type’s input rejects, and store the typed constant. coerce_type passes interval modifiers to input; other length and precision modifiers apply when a row is assigned. The constant keeps a written cast’s modifier when keep_modifier says so.

visit_stored_statement_merges

visit_stored_statement_projections

Visit each select list or RETURNING item of a stored statement before its expression, and each expression in the order of the other visits.
