Here is a new patch version, with several updates.
- Expanded the commit message.
- Added more documentation on storage of virtual columns.
- Added more documentation and tests on security and access privilege
questions. (The functionality itself has not changed.)
- Added support for ALTER TABLE ... SET EXPRESSION.
- Added support for virtual columns in trigger column lists. (For that,
I renamed ExecInitStoredGenerated() to ExecInitGenerated(), which
handles the computation of ri_extraUpdatedCols.)
- Correctly prevent not-null constraints on virtual columns in all cases
(see nearby message).
- Expand virtual columns when checking publication row filter
expressions (see nearby message). Also added tests in 028_row_filter.pl.
According to my notes, this is now feature complete and has no glaring
unsolved problems known to me.
