Re: Migrating to DB2 from Postgres

--Thanks for the reply:

--While trying to see if it's just the sheer size of the file, I
just created one table and put it into a sql file. The statements
are semicolon delimited.

--I'm thinking that the files themselves are just too big. I'm
trying to figure out options, hoping that just connecting to
the Postgres database (and ultimately, the mainframe DB2 server)
will help me in my quest.

--Still looking for documentation and books for this sort of thing.
Suggestions anyone?
