Firebird Foreign Data Wrapper (FDW)
A PostgreSQL foreign data wrapper (FDW) for the Firebird database.
Well I've finally fulfilled one of my 2013 New Year's resolutions, which was to write some kind of foreign data wrapper, so with no further ado here is the initial implementation. It is basically working but is still very much in the proof-of-concept/unstable/may-eat-your-data stage. Having said that, if anyone has a practical use for this I'd be very interested to hear about it - my main motivation for creating this FDW is to learn more about PostgreSQL internals.
