I have restored a Database on FB 1.5.2 which was originally on IB 6.

Working with the data, everyting works ok. However, the database is
still dialect 1. I want to convert to dialect 3 and in order to do so,
I have to change some of the column names.

My problem is with a column named TIMESTAMP. FB refuses to drop that
column saying "Token unknown"

What can I do?

Best regards,
Bengt
