Hi Roman,

I really needed to use this feature, so I downloaded the source code
for version 2.1.2 and fixed the bug. It is found in line 5529 of
main/org/firebirdsql/jdbc/AbstractDatabaseMetaData.java

It should be
return pattern;

instead of
return pattern.toUpperCase();

as described in the bug report http://tracker.firebirdsql.org/browse/JDBC-106

Thanks for everything.

All the best,

Fidel.
