Last weekend I talked with one of the creators of SQLite and was impressed by the thoroughness of their code quality process.
I brushed up a patch that was circulated two years ago and spent a day or so adding error checks and updating documentation. Right now this is a read-only implementation (like mysql/pgsql) but it may be worthwhile to add update support. SQLite implements locking internally. That would allow us to avoid the problems with Postfix's external locks on Berkeley DB maps, which are broken after BDB version 2. The documentation is practically identical to that of MySQL: http://www.porcupine.org/postfix-mirror/sqlite_table.5.html http://www.porcupine.org/postfix-mirror/SQLITE_README.html Wietse
