  That's a simple program which do only
select * from table -> output all records into HTML2 format
(<author>$author</author>\n<title>$title</title>...).

I have about 2M records, average record size is about 500B.  The whole
database size should be 2Mx500=1GB, but for some unknown reason, it simply
take more RAM than real database size.

  Well, I bet it's not doing something back to the future.

  with or without -e work about the same for me, probably due to I have
enough RAM.
