Attached are the v28 patches to implement a subset of Row Pattern
Recognition feature defined in the SQL standard.
In this patch set:
- Reduce the patch size. Comparing with v27, the patch size is trimmed
from 5296 lines down to 5073 lines. This is mainly achieved in the
raw parser patch so that non implemented features are removed from
the grammar file.
- Use newly introduced makeStringInfoExt() instead of makeStringInfo()
in nodeWindowAgg.c, which removes a few unnecessary codes and should
give slightly better performance.
- Fix bugs in the doc and add it more description regarding RPR
syntax.
Best reagards,
