Update of /home/cvsd/slony1/slony1-engine/config
In directory main.slony.info:/tmp/cvs-serv28834/config

Modified Files:
	acx_libpq.m4 
Log Message:
Resolution to bug #46 - incompatibility with PG 8.4.

- Set up autoconf to detect whether or not GetActiveSnapshot() is
  available, and set up #define if it is

- Then config.h.in needs the #define variable, and slony1_funcs.c
  refers to it to control whether it uses the old variable or the
  new function.
