Compiler 5.02 asked me to report a bug.

[Sigbjorn Finne]

Hi,

thanks for a fine bug report. The panic you're running
into is something that could be handled more gracefully
by the compiler.

Workaround is simple, just add -fvia-C to your GHC
command-line.

--sigbjorn

btw, I'd encourage you to make your Postgres Haskell
binding available to other Haskell programmers. Looks
like there's plenty of good stuff in there.
