This patch allows the frame to start from CURRENT ROW (in either RANGE or ROWS mode), and it also adds support for ROWS n PRECEDING and ROWS n FOLLOWING start and end points. (RANGE value PRECEDING/FOLLOWING isn't there yet --- the grammar works, but that's all.) Hitoshi Harada, reviewed by Pavel Stehule

|
* Equality functions to compare node trees.
|
|
*
|
|
* NOTE: we currently support comparing all node types found in parse
|
|
* trees. We do not support comparing executor state trees; there
|
|
* is no need for that, and no point in maintaining all the code that
|
|
* would be needed. We also do not support comparing Path trees, mainly
|
|
* because the circular linkages between RelOptInfo and Path nodes can't
|
|
* be handled easily in a simple depth-first traversal.
|
|
*
|
|
* Currently, in fact, equal() doesn't know how to compare Plan trees
|
|
* either. This might need to be fixed someday.
|
|
*
|
|
* NOTE: it is intentional that parse location fields (in nodes that have
|
|
* one) are not compared. This is because we want, for example, a variable
|
|
* "x" to be considered equal() to another reference to "x" in the query.
