PostgresSQL 8.1 is already in 8.1 Release Candidate.
Are your component able to use new features as in/out parameters?
Will be available new version in near future?
We are testing our provider with PostrgeSQL 8.1. We plan to release a new version that will support PostrgeSQL 8.1 beta4 in near future. Probably it will not support all features of this version. We plan to support all new substantial features of PostgreSQL 8.1 as soon as it will be released.
