No. But I have a header translation for Delphi, that you can compile
with BCB.
Take a look at: http://www.clubdelphi.com/nico/
There's a Postgres section with a link to the file. I haven't tested
it myself because I just have a PC, but some friends have told me that
it works fine.
Let me know if it works for you.
greetings
