Hi, I've had a look at the haskell-hsql-postgresql source - the place where it reads postgres.h and catalog/pg_type.h is where it defines the mapping from haskell datatype -> PostgreSQL datatype. As the package isn't just a client, but an interface driver (apparently using the "binary" wire protocol), it's ok to make it depend on the server headers. Unfortunately there's not really a good place where else to pull this information from. Maybe http://libpqtypes.esilo.com/ would help, but this isn't packaged yet, and would require rewriting hsql-pg. > If there are legitimate reason why this client-side application needs > a server-side header, the package could grow a build dependency on > postgresql-server-dev-9.3 to at least make this fact explicit and fix > the FTBFS in the short term. The OIDs of the exposed datatypes won't ever change, so B-D on postgresql-server-dev-all is safe even if -9.3 will be replaced by -9.4 or later in the future. What worries me, though, is this: Build-Conflicts: postgresql-server-dev-8.3, postgresql-server-dev-8.4 haskell-hsql-postgresql (1.7.3-2) unstable; urgency=low * Make postgresql-server-dev-8.[34] a Build-Conflicts (Closes: 559583) If this package is present at build-time, the resulting ghc-pkg info will reference a directory from it in Includes, causing the installation to fail (see #471786). But if it is not, everything goes well and we have one dependency less. -- Joachim Breitner <nome...@debian.org> Sat, 05 Dec 2009 17:10:34 +0100 I cannot reproduce the problem here with postgresql-server-dev-9.3 installed - the deps of the resulting .debs are the same, but I didn't look into the package for file references in there. B-C on packages that change name with every release seems fragile anyway, so it would best be avoided. Christoph -- c...@df7cb.de | http://www.df7cb.de/
