Module node 

The stored form of an expression, which the catalog keeps for a column default, a check constraint and an index expression.

PostgreSQL stores these as pg_node_tree text that nodeToString writes. rupg stores its own text, which document 05 section 5.2 permits, because clients do not read it. The form looks like the form of PostgreSQL: {NAME :field value ...}. A constant keeps its value in a form that does not change with the settings of the session, so the expression reads back to the same tree.

StoredBound

The stored bound of a partition, as relpartbound keeps a PartitionBoundSpec.

Functions

is_bound

True for the stored form of the bound of a partition, which write_bound made.

read

read_bound

The bound of a stored form that write_bound made.

read_list

The expressions of a stored form that write_list made.

write

The stored form of an expression.

write_bound

The stored form of the bound of a partition, relpartbound. Each constant of the bound is already in the stored form of write().

write_list

The stored form of a list of expressions, such as the expressions of an index: (e1 e2 ...).
