Description (last modified by )
The current RowRange frame is missing handling for several cases.
None of the following are currently supported:
RowRange(start=-2, end=-1)
ROWS BETWEEN 2 PRECEDING AND 1 PRECEDING
RowRange(start=1, end=2)
ROWS BETWEEN 1 FOLLOWING AND 2 FOLLOWING
It's also missing support for EXCLUDE.
ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING EXCLUDE CURRENT ROW
Frame exclusion is supported only in PostgreSQL 11+ and SQLite 3.28+, other databases do not support exclusion (see Oracle 18c doc, MariaDB doc, and MySQL doc).
