hi. one minor issue for ATExecColumnDefault comments.
/*
* ALTER TABLE ALTER COLUMN SET/DROP DEFAULT
*
* Return the address of the affected column.
*/
static ObjectAddress
ATExecColumnDefault(Relation rel, const char *colName,
Node *newDefault, LOCKMODE lockmode)
the comment should be:
* ALTER TABLE ALTER COLUMN SET/DROP DEFAULT
* ALTER VIEW ALTER COLUMN SET/DROP DEFAULT
?
Sometimes, comments are useful for quickly glance at what this function does.
Therefore I guess reword it would be helpful.
