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 PostgreSQL, MySQL, and SQLite.

Assumptions:

• The target database has the right schema, tables, etc, and is empty. See the create scripts in the scripts/ directory.
• Both the source and destination database are called filesender
• SQLite databases are called filesender.sqlite

Postgres to MySQL

Basically Use a shell script one liner:that does:

1. pg_dump
2. Quote field names with backticks
3. Remote any SET statements
4. Remove any SELECT pg_catalog.setval statements
5. Feed INSERT statements into MySQL

You can't simply filter all lines that start with INSERT INTO because the data contains newlines itself.

pg_dump -U username -h hostname -a --inserts filesender |
sed -r 's/^(INSERT\ INTO\ )(files|logs)(\ VALUES\ )/\1`\2`\3/g' |
grepsed --color=never "^INSERT INTO"r '/SET\ ([a-z_]*)\ =\ (.*);/d' |
sed -r '/SELECT\ pg_catalog.setval(.*);/d' |
mysql -u username -h hostname -p filesender

PostgreSQL to SQLite

Largely the same shell script, but no backticks are needed here.

This takes a while depending on the amount of records.

pg_dump -U username -h hostname -a --inserts filesender |
sed -r '/SET\ ([a-z_]*)\ =\ (.*);/d' |
sed -r '/SELECT\ pg_catalog.setval(.*);/d' |
sqlite3 filesender.sqlite

SQLite to PostgreSQL

echo -e ".mode insert files\nSELECT * FROM files;\n.mode insert logs\nSELECT * FROM logs;" |
sqlite filesender.sqlite |
psql -U username -h hostname filesender
