PostgreSQL specific notes

Serial primary keys

PostgreSQL uses the custom SERIAL datatype for defining an auto-incrementing unique column to be used as a primary key. However, this is not an actual datatype but rather shorthand for a more verbose manual command. So (unsurprisingly) DbMover doesn't know what to do with it. Write the more verbose full commands instead:

CREATE SEQUENCE IF NOT EXISTS foo_id_seq;
CREATE TABLE foo (
    id INTEGER NOT NULL PRIMARY KEY DEFAULT NEXTVAL('foo_id_seq'::regclass)
);

Database users and privileges

PostgreSQL's INFORMATION_SCHEMA aliases contain more data than you would define in a schema file, especially for routines (its native functions are also exposed there). You should always run DbMover as a user with privileges for only the database being migrated. All plugins try their best to only work on objects defined as public, but better safe than sorry.

TODO/wishlist

Support for enums

These are implemented in Postgres as a sort of custom data types. Support is on the roadmap, but since I personally never use them it's not very high on my (annoyingly long) list of priorities :)
