3  * equalfuncs.c
4  * Equality functions to compare node trees.
5  *
6  * NOTE: we currently support comparing all node types found in parse
7  * trees. We do not support comparing 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 comparing 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.
12  *
13  * Currently, in fact, equal() doesn't know how to compare Plan trees
14  * either. This might need to be fixed someday.
15  *
16  * NOTE: it is intentional that parse location fields (in nodes that have
17  * one) are not compared. This is because we want, for example, a variable
18  * "x" to be considered equal() to another reference to "x" in the query.
