• 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

Shell Use a shell script that does:

1. pg_dump
2. Quote field names with backticks
3. Remote any SET statements
4. Remove any SELCT SELECT pg_catalog.setvalstatements
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 -t 'files' -t 'logs' filesender |
sed -r 's/^(INSERT\ INTO\ )(files|logs)(\ VALUES\ )/\1`\2`\3/g' |
sed -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 '/^INSERT INTO (file|log)s/!d' |
sed -r '/SET\ ([a-z_]*)\ =\ (.*);/d' |
sed -r '/SELECT\ pg_catalog.setval(.*);/d' |
