(Back from 2 weeks without computers)
Hmm, calendar isn't that broken :)
As for Oracle: I always added/changed the respective Oracle query when I had worked on the corresponding PostgreSQL query. There shouldn't be missing Oracle queries, just some queries that bump.
Now that I have additionally installed Oracle 8i on my box here (where is the much desired Oracle 9i support?), I fixed the broken Oracle queries and committed them tonight.
Needless to say: any help is appreciated.
