I've managed to resolve this issue. I'm not sure how I ended up with this issue, but in case anyone else get's hit by it, here's what I've learned:

-At version 0.6, SQLAlchemy changed the format for connecting to postgresql:

[postgresql] The "postgres" dialect is now named "postgresql"

-I somehow managed to get multiple eggs pointing to different versions of SQLAlchemy:

[galaxy@login002 galaxy-dist]$ ls eggs/SQLAlchemy-0.

SQLAlchemy-0.5.6_dev_r6498-py2.5.egg/

SQLAlchemy-0.5.6_dev_r6498-py2.7.egg/

SQLAlchemy-0.7.9-py2.7-linux-x86_64-ucs2.egg

-During my early stages of rolling out Galaxy, I managed to use the 0.7.9 version of SQLAlchemy which forced me to change my database_connection syntax:

[galaxy@login002 galaxy-dist]$ ./run.sh --daemon

-this updates some of the "eggs"

-it doesn't start; check the logs:

[galaxy@login002 galaxy-dist]$ tail paster.log

...

ile__', None ), self.config.database_engine_options, app=self )

/home/galaxy/galaxy-dist/eggs/SQLAlchemy-0.7.9-py2.7-linux-x86_64-ucs2.egg/sqlalchemy/engine/url.py:105: SADeprecationWarning: The SQLAlchemy PostgreSQL dialect has been renamed from 'postgres' to 'postgresql'. The new URL format is postgresql[+driver]://<user>:<pass>@<host>/<dbname>

-at that point I changed my database_connection from:

database_connection = postgres://

to:

database_connection = postgresql://

and everything appeared to be happy. Everything that is except for the cleanup script.

-I've now changed everything to: database_connection = postgres:// and everything appears to be happy.

I really don't understand how this came out. I was using postgresql:// for quite a while without issues, so it would seem that I could *not* have been using 0.5.6 of SQLAlchemy unless this was modified by the Galaxy community.

Cheers,

Malcolm

I noticed yet another version of cleanup_datasets.py under cron which looks like it might be compatible with postgres, but am leary of trying it as I'm not sure what it means by "1: database directory to clean". I'm not sure what directory to point this to, nor am I confident that just deleting data from the directory is the safest thing.
