Hello!

It's very important to have place to store table metainformation. In all
common DBMSs we can use TABLE/COLUMN COMMENT as meta description of table
but SQLite doesn't support it.

COMMENTs are supported from very old to new PostgreSQL:
http://www.postgresql.org/docs/7.1/static/sql-comment.html
http://www.postgresql.org/docs/9.2/static/sql-comment.html

MySQL:
http://dev.mysql.com/doc/refman/5.1/en/create-table.html

ORACLE:
http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_4009.htm

IBM DB2:

Sybase:

P.S.  Field type is bad storage for additional information because there
are a lot of conversion problems from some bindings (including official
tclsqlite) when column types are non-standard.
