pg_node_tree
An internal data type to represent nodeToString output
pg_node_tree is an internal data type to represent nodeToString output.
It was added so that system catalogue tables can safely store nodeToString output for passing to pg_get_expr().
Usage
pg_node_tree is used in the following system catalogue tables:
- pg_attrdef
- pg_class
- pg_constraint
- pg_index
- pg_partitioned_table
- pg_policy
- pg_proc
- pg_rewrite
- pg_trigger
- pg_type
Change history
