Log Message:
-----------
Remove transformAlterTableStmt's kluge to replace ColumnDef.is_not_null
flags by separate AT_SetNotNull subcommands. That was always ugly and
inefficient, and it's now clear that it was merely a partial workaround
for the bug just identified in ATExecAddColumn. This is just code
beautification not a bug fix, so no back-patch.
Brendan Jurd, with some trivial additional cleanup by me.
