Sorry for the delay - I was waiting for the import to complete.  It
took from Dec 30 15:00 through Jan 06 10:49, i. e. nearly 7 days.  I
will have to test how long the import of a PostgreSQL dump will take,
hopefully it's faster (otherwise recovery after a crash of the DB
server will be a real PITA).

So the import completet, but it threw some 300+ error messages,
apparently for file names which have an apostrophe in their names.

For example the SQL statement:

INSERT INTO Filename (FilenameId, Name) VALUES 
(706893,'Multichannel_DMA_API_User\'s_Guide.pdf');

will raise:

ERROR:  syntax error at or near "s_Guide"
LINE 1: ... Name) VALUES (313896,'Multichannel_DMA_API_User\'s_Guide.pd...
                                                             ^

Can anybody please tell me what this statement should look like so it
gets digested by PostgrSQL?  Thanks in advance...

You are definitely right here.  But the hints I get there are not
really helpful, at least not to me - I ain't no DB expert after all.


Thanks.

Best regards,
