Yes, the limitation is still there. There have been some talks amongst
the Firebird developers on how to increase it, but they're not
conclusive at the moment. Also, if you didn't know, an SQL statement
can only be at the most 32K characters. It's a limitation at the
moment. Also, it is possible to have multiple IN clauses in a query,
up to the statement size limitation.
