Problem is, it requires parsing the CREATE command looking for comments in a
certain format. Notoriously difficult, considering that they can contain CR,
LF, tab, and unforeseen Unicode characters.
I’m utterly against anything that tries to read C-style comments. Comments are
comments. Computers are meant to ignore them to the point that they don’t even
know they exist.
On the other hand, if we establish a standard for storing comments in database
tables — which would require a consistent table name, column names, and values
— it might take too much extra time to show those comments as an extra column
in the response to PRAGMA tale_info() and similar PRAGMAs. But I think it’s
overkill. Anyone who would want that would know how to retrieve the
