Notes:
|
|
- No its not perfect
|
|
- Yes it discards ALL stored procedures
|
|
- Yes it discards ALL queries except for CREATE TABLE and INSERT INTO
|
|
- If you're having problems creating your postgres dump, make sure you use "--format p --inserts"
|
|
- Default output engine if not specified is InnoDB
