Hey, that is a very cool product!

I had not encountered SQLite before.  I downloaded it just to take a peek,
and I noticed the doc said that the DML was mostly compatible with
Postgres, so I took a dump of my non-trivial Postgres database and fed it
directly into SQLite.  As the README said, it objected to a few PG syntax
extensions, but to my rather great surprise, it basically sucked up the
whole database.  It imported all the tables and all the data, and I was
able to perform some rather sophisticated queries without trouble.

I'm very impressed.  It took a long time to do the import, but the
resulting data file was much smaller than my PG files.  I can think of a
number of interesting applications for this.

Thanks for the pointer.
