Finally, I installed the latest CVS checkout. I uninstalled my previous pgpool-II build by doing:
[root ~]# make uninstall [user ~]# make clean Then, went to the just downloaded repository for pgpool-II and did: [user ~]# ./configure [user ~]# make [root ~]# make install Tried the below same thing, but now db connection through pgpool blocks as soon as second backend goes from status 2 to 3. Anything wrong with the way I installed the most recent CVS head?

Thanks for the report. I think it's a bug with CVS Head. pgpool should fail over in this case. Fix was committed. Could you please try it out? -- Tatsuo Ishii SRA OSS, Inc.
