Anyone else as enthused as I am about Pg-Logical and tried installing both version on same host? Fails on the output plugin package due to header file conflict. I recall as might be expected that the reverse is true also. If you wipe 9.5 and then install 9.4 it works then you get borked trying to install the 9.5 version. I wonder if those headers should be packaged down into a version numbered directory? # uname -a Linux jerry 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux # # echo $#; echo $* 4 postgresql-9.4-pglogical postgresql-9.4-pglogical-output postgresql-9.5-pglogical postgresql-9.5-pglogical-output # dpkg -l | grep pglogical ii postgresql-9.5-pglogical 1.0.1-1wheezy amd64 PGLogical plugin for PostgreSQL 9.5 ii postgresql-9.5-pglogical-output 1.0.1-1wheezy amd64 PGLogical Output plugin for PostgreSQL 9.5 # apt-get install -y $1 Reading package lists...
