Due to the way it was first implemented, the "username" column would be on a different position depending on if it was an extension upgrade or a fresh install. This caused problems with pg_dumping databases and restoring them. pg_dump does not include the extension source (so this table's schema is not included on the dump) but does include this contents, using a COPY without column names by default and failing due to the order difference. After this has run, all tables (whether updated or not) will have the "username" column on the last position.

PostgreSQL extension for CartoDB
See the cartodb-postgresql wiki.
Dependencies
- PostgreSQL 9.3+ (with plpythonu extension and xml support)
- PostGIS extension
Install
make all install
Test installation
make installcheck
NOTE: you need to run the installcheck as a superuser, use PGUSER env variable if needed, like: PGUSER=postgres make installcheck
NOTE: the tests need to run against a clean postgres instance, if you have some roles already created test will likely fail due publicuser not being dropped.
Enable database
In a database that needs to be turned into a "cartodb" user database, run:
CREATE EXTENSION postgis;
CREATE EXTENSION cartodb;
Migrate existing cartodb database
When upgrading an existing cartodb user database, the cartodb extension
can be migrated from the "unpackaged" version. The procedure will copy
the data from public.CDB_TableMetada to cartodb.CDB_TableMetadata,
re-cartodbfy all tables using old functions in triggers and drop the
cartodb functions from the 'public' schema. All new cartodb objects will
be in the "cartodb" schema.
CREATE EXTENSION postgis FROM unpackaged;
CREATE EXTENSION cartodb FROM unpackaged;
Update cartodb extension
Updating the version of cartodb extension installed in a database is done using ALTER EXTENSION.
ALTER EXTENSION cartodb UPDATE TO '0.1.1';
The target version needs to be installed on the system first (see Install section).
If the "TO 'x.y.z'" part is omitted, the extension will be updated to the latest installed version, which you can find with the following command:
grep default_version `pg_config --sharedir`/extension/cartodb.control
Updates are performed by PostgreSQL by loading one or more migration scripts as needed to go from the installed version S to the target version T. All migration scripts are in the "extension" directory of PostgreSQL:
ls `pg_config --sharedir`/extension/cartodb*
During development the cartodb extension version doesn't change with every commit, so testing latest change requires special steps documented in the CONTRIBUTING document, under "Testing changes live".
Limitations
- The main schema of an organization user must have one only owner (the user).
