FileSender supports several different database back-ends, by virtue of PHP's PDO.

Currently there are 3 back-ends that are known to work: Postgres, MySQL, and SQLite.

Assumptions:

Postgres to MySQL

Basically a shell script one liner:

pg_dump -U username -h hostname -a --inserts filesender |
sed -r 's/^(INSERT\ INTO\ )(files|logs)(\ VALUES\ )/\1`\2`\3/g' |
grep --color=never "^INSERT INTO" |
mysql -u username -h hostname -p filesender
