I have created v48 RPR (Row pattern recognition) patches based on the
attached incremental patches against v47 patches. I have briefly
looked through all the incremental patches. If I have missed
something, I will follow up later. The patches are based on the
commit 3e3d7875e95 on the master branch.
The series of patches are to implement the row pattern recognition
(SQL/RPR) feature. Currently the implementation is a subset of SQL/RPR
(ISO/IEC 19075-2:2016). Namely, implementation of some features of
R020 (WINDOW clause). R010 (MATCH_RECOGNIZE) is out of the scope of
the patches.
