3 * copyfuncs.c
4 * Copy functions for Postgres tree nodes.
5 *
6 * NOTE: we currently support copying all node types found in parse and
7 * plan trees. We do not support copying executor state trees; there
8 * is no need for that, and no point in maintaining all the code that
9 * would be needed. We also do not support copying Path trees, mainly
10 * because the circular linkages between RelOptInfo and Path nodes can't
11 * be handled easily in a simple depth-first traversal.
