bpchat cannot exceed 10485760

Greetings,

   I am migrating a database from HSQLDB to Postgresql. I am using the
   HSQL Database manager to transfer my data from HSQL to postgres and
   found a hurdle. I hope this is not a bug. I have approx 50MB of SQL
   database in HSQL. After doing a "transfer" of some tables it stops
   transfer for the rest crying "bpchar cannot be greater than a
   *certain* size". *certain* - >  approx 10 million or greater. I tried
   transferring one of the problematic table (using dbmanager) and it
   fails as well with same error.

   The exact error message is as follows.




org.hsqldb.util.DataAccessPointException: ERROR:  length for type bpchar
cannot exceed 10485760

      I assumed it was an HSQL bug, but I hacked a little more and find
      that there is probably a postgresql involved in this problem.

   Any clues or pointers on how should I transfer the data? Or some
   pointers on where the problem actually is would be of great help.
