Hi,

> INFORMATION_SCHEMA.lobs table grows rapidly

Yes. This is a problem for both MVStore and PageStore. The problem is that
CLOB and BLOB objects must still be available even after the transaction is
complete, and I think even after the result set is closed. And even after
the row is removed. In previous versions of H2, BLOB and CLOB objects were
removed too early; now they are removed when the database is closed. This
will fix the "LOB is removed" problem, but results in a growing LOB table,
which contains references (table -3 is temporary lobs).

This is a problem, and I don't have a good solution for that I'm afraid.
Closing the database or closing the connection from time to time are not
good solutions I think.

Maybe the temporary BLOB and CLOB objects should have a timeout (of let's
say 1 minute by default)?

Regards,
Thomas
