pgdump
add backticks to field values
...
Use a shell script that does:
- pg_dump
- Quote field names with backticks
- Remote any SET statements
...
- Remove any
...
- SELECT pg_catalog.setvalstatements
- Feed INSERT statements into MySQL
You can't simply filter all lines that start with INSERT INTO because the data contains newlines itself.
