Problems with linking against PostgreSQL 8.4 - Mailing list pgsql-odbc

Hi, I tried to build the latest git version of postgresql odbc driver and
(even if the build seems to be complete) there is a linkage problem:

  $ ldd -r ./.libs/psqlodbcw.so > /dev/null
  undefined symbol: PQconnectdbParams     (./.libs/psqlodbcw.so)

I see that the symbol was added to PostgreSQL project in ~2010 and it
seems to be a problem.  Should I expect that newer drivers are able to be
run against older (still supported by PostgreSQL community) PostgreSQL
server, namely 8.4.13?

If that ^^ is a problem, could you please fix that?  I could possibly look
at some configure.ac/#ifdef solution and propose a patch if you are not
against that..

Thanks, Pavel
