Pg-Logical output pkg; can't install 9.4 and 9.5 on same Wheezy box - Mailing list pgsql-general

Posted to Admin a few days ago...  I'll try here next before going to
Hackers or trying to locate the packagers.

----

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?
